delivered the opinion of the Court.
STATEMENT OF THE CASE
On 6 Fеbruary 1975 two petitions were filed in the Circuit Court for Kent County, sitting as a Juvenile Court, against appellant, 1 a youth then seventeen years of age. Both alleged *133 that he was a delinquent child. 2 One gave as reason that on 9 July 1974 he had stolen a bike belonging to C. Daniel Saunders (Code, art. 27, § 340). The other gave as reasons that on 12 December 1974 he had (1) received a pair of binoculars belonging to George Outten, knowing them to have been stolen (Code, art. 27, § 467), and (2) stolen the binoculars (Code, art. 27, § 341). The petitioner in each petition was William T. Blackiston, Jr., Deputy Sheriff of Kent County. At an adjudicatory hearing which terminated on 3 March 1975, the court found under the petition concerning the binoculars that appellant was a delinquent child. It dismissed the petition concerning the bike. At a dispositional hearing on 20 March 1975 appellant was committed to the Secretary of Health and Mental Hygiene for placement at Maryland Training School. The Secretary was directed to provide psychiatric and psychological services. An appeal was noted.
THE CONFESSION
Background
At the adjudicatory hearing, 3 a confession obtained by the authorities from appellant was challenged. Evidence was received on the motion to suppress it. On 11 July 1974 Saunders reported the theft of his bike to the office of the *134 Sheriff for Kent County. On 12 December 1975 Outten reported to that office that his home had been broken and entered and that personal property had been stolen. Blackiston and Deputy Sheriff Jess Metcalfe investigated the crimes. Their investigation led them to appellant, one of a group of suspects. On 18 January 1975, about 4:00 p.m., Blackiston and Metcalfe, in uniform and wearing side-arms, went in their official car to the trailer home whеre appellant lived with his parents. Appellant was the first “suspect” they went to see. Blackiston said: “I wasn’t sure he was my man. I wanted to investigate to find out who was.” The deputies told the parents they wanted to see appellant. Appellant appeared from within the trailer, and Blackiston took him to the car parked nearby to interrogate him. Blackiston testified that he did this “Because it’s generally my policy to do an interrogation on my grounds.”
Appellant was born in January 1958. At age 8 years and 10 months he was in the second grade in a school in Wilmington and was given an I.Q. test known as the WISC (Western Intelligence Scale for Children). His verbal score was 74, performance was 78 and full scale I.Q. was 73. The next year he was placed in the “Special and Emotionally Maladjusted” third grade class in a Kent County school. In 1968, 1969 and 1970 he was in primary “special education” at Millington. “Special education” was “a special placement in classes for children who cannot function or get along in a regular class for various reasons.” In May 1971 he was again given the WISC test and also an achievement test known as WRAT. On the former his verbal score was 75, his performance quotient was 92 and his full scale I.Q. was 81. On the WRAT test his reading level was 3.9, spelling was 4.3 and arithmetic was 3.3. In 1971 he attended the sixth grade at Galena Middle School. He was present 66 days and absent 8 days. He withdrew and his records were sent to Chestertown Middle School on 3 January 1972, although it seems that he did not attend that school. On 14 February he was transferred to Cambridge State Hospital where he remained until 27 March 1974, when he was discharged to his parents. There were home visits, so that thе actual time spent in that Institution *135 was about one year and four months. 4 The Institution’s final diagnoses on discharge included “adjustment reaction of adolescence, conduct disturbance” and “borderline mental retardation with other (and unspecified) condition.” 5 The condition on release and prognosis was, “Patient’s condition on leaving was excellent from the physical and psychiatric viewpoint. However, prognosis is considered guarded if patient doesn’t have enough supervision at home and if he doesn’t have a job in the community.” Appellant did not return to school. This was the background of the youth Blackiston took to the police car to interrogate.
Circumstances Surrounding the Obtaining of the Confession
Blackiston sat in the front seat and placed appellant in the back seat. Blackiston testified that he read all the Miranda warnings to appellant and that appellant said he understood them. “And I said, ‘Do you knowingly waive these rights?’ and [appellant] didn’t know what the words ‘knowingly waive’ meant, so I explained to him that if he wanted to talk to me about Mr. Outten’s property he could stop any time and not tell me anything. And he advised me okay.” There was evidence tending to show that the confession was voluntarily in the traditional sense. Blackiston said that neither he nor Metcalfe made any threats, gave any promises or extended any inducements to appellant to get him to talk. Metcalfe, who had remained at the trailer to talk to the parents, appeared about the time Blackiston finished giving the Miranda warnings and sat in the front *136 seat next to Blackiston. The interrogation proceeded. Appellant gave a verbal statement.
Appellant’s father gave his version of what occurred:
“He drove up to the yard and my wife went to the door and sаid a Trooper car was here, and I said, ‘What - Trooper,’ and she said, ‘From Maryland.’ Then they came up to the door and one had his hat on [apparently Blackiston] and the other one didn’t. Before he knocked on the door she opened the door. And he said — I can’t tell one from the other, but the one that had the hat on said, ‘Could I talk to Stanford?’, and she said, ‘Come on in.’ They came in and the short one, the one that didn’t have the hat on, wasn’t completely in the door. My wife called to [appellant], he was in the back, in the back bedroom and he came out of the trailer on thé porch part. She said to him, ‘They want to talk with you.’ Then the one that had the hat on said, ‘Boy, go to the car.’ They went on to the car. Then the one that didn’t have the hat on, he went out first. He was the last one getting in thе car. I watched out the window.”
He denied that the deputies told them why they wanted to talk to appellant.
Appellant told what occurred when the deputies arrived:
“I was in the bedroom, in the back bedroom in the trailer, getting my.shirt. Then my mother called me out there on the porch because the policemen was there. Then the young one, with the hat on, asked my father could he ask me some questions. The one in the doorway didn’t say anything. Then we went out into the car and that was when he started asking me questions.”
According to appellant, he, Blackiston and Metcalfe went out to the car at the same time. Metcalfe said, addressing appellant by his first name, “_, we’ve got some trouble around here and I think you know about it.” Then *137 Blackiston “started reading off my rights.” Appellant denied, however, that anything was said about a lawyer. He said he went with the “policemen” beсause he was afraid they would take him to Chestertown and lock him up. 6 On cross-examination the State pursued the matter of the voluntariness of the statement in the traditional sense:
“Q. Now, did they ever threaten to hit you?
A. No sir.
Q. Or beat you?
A. No sir.
Q. Did they make any promises or do anything to you that was bad?
A. No sir.”
Blackiston was recalled by the State. He said that when he and appellant went to the car, Metcalfe remained at the trailer to talk to the parents. About ten or fifteen minutes elapsed before Metcalfe came to the car. Blackiston said that when he and appellant first arrived at the car “I introduced myself and advised [appellant] that I wanted to talk to him about George Outten’s home being broken into and some things being taken.” Blackiston iterated that he then gave the Miranda warnings, and that appellant said he understood them and waived them. On cross-examination, asked why he did not talk to appellant in the trailer about the Outten matter, Blackiston replied: “I do it differently at times, but I generally take the people out in the car to talk.” He said he tried “to deal with” both adults and juveniles the same way.
*138 Admissibility of the Confession
The judge below granted the motion to suppress the confession. Upon our independent constitutional appraisal, see
Davis v. North Carolina,
The judge below apparently relied on the failure to show a valid waiver of the constitutional privilege against self-incrimination and right to counsel in holding that the confession was to be excluded. We are in accord. The rule of
Miranda v. Arizona,
*140 The alternative reason why we think the confession here was inadmissible requires a look at the doctrine of the fruit of the poisonous tree as it applies in Maryland.
On 14 January 1963 the Supreme Court of the United States decided
Wong Sun v. United States,
“We need not hold that all evidence is ‘fruit of the рoisonous tree’ simply because it would not have come to light but .for the illegal actions of the police. *141 Rather, the more apt question in such a case is ‘whether, granting establishment of the primary illegality, the evidence to which instant objection is made has been come at by exploitation of that illegality or instead by means sufficiently distinguishable to be purged of the primary taint.’ ”
Although the Fourth Amendment was held to apply to the states through the Fourteenth Amendment,
Mapp v. Ohio,
*142
It now appears that the Supreme Court always deemed
Wong Sun
controlling in state prosecutions. On 26 June 1975 it decided
Brown v. Illinois,
*143
We have indicated that the confession was obtained from appellant during a “custodial interrogation” of him within the contemplation of
Miranda.
We think also that appellant was in custody at the time within the contemplation of
Wong Sun.
When Blackiston took appellant to the car and placed him in the back seat in order to interrogate him, appellant was deprived of his freedom of action in a significant way and was, in fact, being detained. We do not think that a full-fledged arrest is a prerequisite of the application of the
Wong Sun
doctrine. Cf.
Morales v. New York,
Courts Art. § 3-821, as in effect on 18 January 1975, provided:
“A child may be taken into custody:
(1) Pursuant to the order of the court under the provisions of this subtitle;
(2) Pursuant to the law of arrest;
(3) By a law enforcement officer or other person authorized by the court when he has reasonable grounds to believe that the child is in immediate danger from his surroundings and that his removal is necessary for his protection; or
(4) By a law enforcement officer or other person authorized by the court when he has reasonable grounds to believe that the child has run away from his parents, guardian, or legal custodian.”
It is clear that appellant wras not taken into custody under (1), (3) or (4) of the statute. Nor is there any indication that а warrant had been issued for his arrest. Further, the record does not reflect that the deputies had probable cause for a warrantless arrest. Blackiston said that after a report of the crimes had been received from the victims, an investigation was made, after which he and Metcalfe went to talk to appellant. Asked if he went to appellant’s home “for the possibility of having him confess to the crime of B & E’s around in that area”, Blackiston said, “Not at first. I went
*144
there to investigate a crime that took place and wanted to know what he knew about it. I never know whether they will confess or not.”
10
Metcalfe said they “had reason to think” appellant was involved in the breaking of the Outten home and that they “understood” that appellant “had been riding around Golts” (the place where aрpellant lived), on a bike similar to the stolen one. This, absent further explanation, is obviously so insufficient to constitute probable cau.se for an arrest that discussion is unwarranted.*
11
See
Stanley v. State,
Having found that the detention of appellant was illegal, we consider next the effect of this illegal conduct by the authorities on the admissibility of the confession. In
Ryon secundus
we found
from Wong Sun
and the cases related thereto, that statements obtained following an illegal detention were not rendered inadmissible simply because of that illegality, nor were they rendered admissible simply because the
Miranda
warnings were fully given.
(a) the voluntariness of the statement, which is a threshold requirement;
*145 (b) compliance with the Miranda safeguards, which is as important in determining whether the statements were obtained by exploitation of the illegal conduct;
(c) other relevant factors, such as
(i) the temporal proximity of the detention and the confession;
(ii) the presence of intervening circumstances;
(iii) the purpose and flagrancy of the official misconduct.
In the context of this second reason why the confession was inadmissible, that it was the fruit of a poisonous tree, we assume, for the purpose of decision that the statement was voluntary, and that there was full compliance with the Miranda safeguards. We, therefore, look to the other relevant factors. The confession followed close upon the heels of the illegal detention; there was no significant time lapse. There were no circumstances intervening between detention and the confession. The admitted purpose of the detention was to interrogate and the taking of appellant to the car from his home and the presence of his parents was patently flagrant, the admitted purpose being so the interrogation of appellant could be on Blackiston’s own grounds. Thus, the confession was come at by exploitation of the illegality of the detention and not by means sufficiently distinguishable to be purged of the primary taint. Therefore, the confession was inadmissible.
THE TANGIBLE EVIDENCE
Immediately after obtaining a statement from appellant in the car, the deputies and appellant returned to the trailer. Blackiston asked the parents whether they had seen appellant with a pair of binoculars. The father replied that he had seen binoculars in appellant’s possession “the other day” and said to appellant, “Boy, ya tell the man where ya have them if you got it around here.” Blackiston’s version of what happened next was that appellant fetched the binoculars from somewhere in the trailer. The father’s *146 version as given at the hearing was that appellant’s mother found the binoculars and gave them to the police. On the record before us, it appeared that the inquiry about the binoculars stemmed from appellant’s statemеnt to the deputies. That is, from the record, we can only conclude that the deputies were led to the binoculars by what appellant told them. There was no evidence sufficient to establish that the deputies learned of the binoculars from a source independent of the confession. Blackiston testified that Outten made a complaint but the records regarding it were not produced. He also said that Outten told them what had been stolen, and that Metcalfe made a list of the articles as described by Outten, but the record is completely silent as to what articles were listed. The record just does not disclose that the authorities knew that binoculars had been stolen from Outten or that they had reason to believe that they were in the possession of the appellant, one of a numbеr of suspects, until they obtained the confession. The deputies did not inquire about or seek the binoculars until they interrogated appellant but they did make inquiry and seek them immediately thereafter. The short of it is that, on the evidence, the binoculars were obtained through the confession and were a fruit of it. There was a causal connection between the confession and the tangible evidence which was not broken.
QUESTION FOR DECISION
The question for decision on this appeal is whether, upon proper identification, the binoculars were admissible in evidence at the adjudicatory state of the delinquency hearing.
DECISION
The court below, not having the benefit of Brown, Everhart or our second Ryon opinion, admitted the binoculars in evidence over objection, stating, “It seems to me that based on the testimony thus far that these have come into the hands of the police without any violations of *147 anybody’s constitutional rights.” 12 Wong Sun and its progeny teach us to the contrary.
I
We look first at the admissibility of the binoculars in the frame of reference of the primary illegality being an unauthorized detention. When official misconduct resulting in the primary taint is an unreasonable search and seizure or an illegal arrest or an unauthorized detention, the Fourth Amendment is invoked. Violation of the Fourth Amendment right brings into play the exclusionary rule. The exclusionary rule applies to render inadmissible both tangible evidence and testimonial evidence derived from the official misconduct and tainted thereby.
In the case sub judice, granting the primary illegality, namely, that the detention of appellant was unauthorized, it followed that not only the subsequent confession was illegal, as we have indicated, but also that the binoculars improperly came into the possession of the deputies. The testimonial еvidence derived from the detention, and the tangible evidence derived from the testimonial evidence. In other words, the detention led to the confession and the confession led to the binoculars. Each was the immediate, direct and proximate cause of the other with no break in the causal connection by time or circumstances. The primary taint flowed down to the confession and from it to the binoculars. The State did not establish that the binoculars were come at by means sufficiently distinguishable to be purged of the primary taint. Under the Wong Sun doctrine, the binoculars were inadmissible in the hearing on the delinquency of appellant, and we so hold.
II
We next look at the admissibility of the binoculars in the frame of reference of the primary illegality being the *148 obtaining of the confession from appellant. As we have indicated, an alternative reason why the confession was inadmissible was that it was obtained without an effective waiver of the Miranda rights. This official misconduct invoked the Fifth Amendment. The question is whether the Wong Sun doctrine applies when the primary illegality is a violation of the Fifth Amendment privilege against self-incrimination. The State argues- strongly that it does not. It points out: “In Carter and Everhart, the Court of Appeals had adopted the ‘fruit of the poisonous tree’ analogy in the context of illegal searches and seizures.” It asserts: “No decision in this State, however, has mandated the application of that doctrine where the poisonous tree has Fifth Amendment roots.” 13 It cites and'quotes from George, The Fruits of Miranda: Scope of the Exclusionary Rule, 39 Colo.L.Rev. 478 (1967). Professor George, who believed that “to exclude derivative evidence on the strength of Miranda is to push the decision to its outer limits.” Id., at 489-491. He would not exclude any evidence discovered as the result of a coerced confession. The State quotes in J. Cook, Constitutional Rights of the Accused — Trial Rights, § 97 at 362 (1974), entitled “Fruits of an illegal confession”:
“Once it is determined that a statement was improperly obtained from an accused, it follows that any other evidence obtained as a result of the illegality is equally inadmissible. Thus, a confession ostensibly valid may be inadmissible by virtue of the taint of a previously improperly obtained confession.”
It answers this assertion by observing that “[n]early all the cases cited by Cook to support his position, however, involve subsequent confessions tainted by previous improperly obtained confessions. Only a few involve the exclusion of tangible evidence the existence of which was uncovered through an illegal interrogation.” We are not persuaded to adopt the Stаte’s view.
*149
Miranda,
at 479, declared flatly that until its required warnings and waiver are demonstrated by the prosecution at trial, “no evidence obtained as a result of interrogation can be used against him.” It warned,
id.,
n. 48, at 479: “In accordance with our holdings today and in Escobedo v. State of Illinois,
“Some comments in the Miranda opinion can indeed be read as indicating a bar to use of an uncounseled statement for any purpose, but discussion of that issue was not at all necessary to the Court’s holding and cannot be regarded as controlling. ... It does not follow from Miranda that evidence inаdmissible against an accused in the prosecution’s case in chief is barred for all purposes, provided of course that the trustworthiness of the evidence satisfies legal standards.”
Then in
Michigan v. Tucker,
Far from limiting the
Wong Sun
doctrine to Fourth Amendment violations,
Tucker
expressly invited the application of that doctrine to Fifth Amendment violations in a proper case. The Court,
“ ‘The rule is calculated to prevent, not to repair. *151 Its purpose is to deter — to compel respect for the constitutional guaranty in the only effectively available way — by removing the incentive to disregard it.’ Elkins v. United States,364 U. S. 206 , 217,80 S. Ct. 1437 , 1444,4 L.Ed.2d 1669 (1960).”
Then the Court in Tucker declared, at 2365:
“In a proper case this rationale would seem applicable to the Fifth Amendment context as well.”
We think the case before us is such a proper case.
The weight of authority in other jurisdictions considering the admissibility of tangible evidence derived from statements unlawfully obtained is that such evidence is not admissible.
People v. Paulin,
In
United States v. Castellana,
We hold that, on the recоrd before us, the admission of the binoculars in evidence at the adjudicatory hearing was error requiring reversal of the judgment. We reverse it, and grant a new trial.
In view of our holding, we do not reach appellant’s second question concerning the sufficiency of the evidence.
Judgment reversed; case remanded for a new trial.

. “ ‘Delinquent child’ means a child who commits a delinquent act and who requires supervision, treatment, or rehabilitation.” Courts Art. § 3-801 (k).
“ ‘Delinquent Act’ means ... an act which would be a crime if done by a person who is not a child.” Courts Art. § 3-801 (j). See ch. 554, Acts 1975, effective 1 July 1975.
. We note that in a delinquency hearing, pursuant to the Maryland Rules of Procedure in effect at the time of the hearing here, the State’s attorney shall preparе and present the testimony in behalf of tbe petitioner unless excused by the court. Rule 912 b. The rules of evidence applicable to criminal cases shall apply. Rule 912 c. The alleged delinquent may remain silent as of right and shall be so advised. Rule 917. The allegations must be proved beyond a reasonable doubt, and an uncorroborated confession made by a child out of court is not sufficient proof of delinquency. Courts Art. § 3-830 (a). The Court of Appeals, by order dated 18 June 1975, approved and adopted, effective 1 July 1975, a revision of chapter 900, made necessary by an enactment of a new statewide Juvenile Code by ch. 554, Acts 1975, §§ 3-801 to 3-833 of the Courts Article, effective 1 July 1975.
. The court observed: “[T]he Court knows the circumstances of [appellant’s] stay at the hospital. He was sent for evaluatiоn and due to his getting lost by the Courts or by Juvenile Services, or by someone, and due to the staff at the hospital feeling that he needed treatment, they didn’t submit a report to the Court, and continued to just keep him, that’s all. What’s the date? That’s February of ’72 I believe, and they didn’t submit a report until July 26th, ’72. And it refers to a conversation, and I am sure was the result of my conversation with Dr. English or Dr. Culloda, and I can’t recall which now, it was agreed we let him stay there. So I say all of this for record purposes and so that things won’t appear in a different light than the true light of this case. That’s all.”
. There were two other diagnoses: “hypochromic anemia, treated”, and “adolescent gynecomastia, etiology unknown.”
. The judge inquired about this statement. The transcript reads:
“Judge Rasin: Why do you think they were going to do that? Do you think a policeman, every timе you see one, is going to lock you up?
A. They seem to aways have some reason.
Judge Rasin: Do you mean whenever a policeman sees you he seems to have some reason to lock you up?
A. Around here.”
. The Court said in Wong Sun, at 486: “Either in terms of deterring lawless conduct by federal officers, ... or of closing the doors of the federal courts to any úse of evidence unconstitutionally obtained,... the danger in relaxing the exclusionary rules in the case of verbal evidence would seem too great to warrant introducing such a distinction.”
. The Court said,
. Neither Brown v. Illinois,
supra,
nor Everhart v. State,
supra
mentioned the question of retroactive application of their respective decisions. It is manifest, however, from the mandate of the Supreme Court to us in Ryon, that
Brown
is to apply, at the least, to cases not finally litigated at the time of the
Brown
decision. We said in Greene v. State,
. In Brown v. Illinois, supra, at 2262, the Court noted the impropriety of an arrest “for investigation” or for “quеstioning.”
. Mere suspicion is not the equivalent of sufficient probable cause. Henry v. United States,
. The court admitted the binoculars “subject to exception. . . . We will see what the defense has to say about them.” The binoculars remained in evidence.
. Of course, as we have indicated, it has been only a few months since it was recognized in this jurisdiction that Wong Sun applies in state prosecutions.
. The defendant’s interrogation took place prior to
Miranda
but his trial was afterwards. Therefore,
Miranda
applied. Johnson v. New Jersey,
. The Supreme Court rejected a suggestion “that courts should exclude evidence derived from ‘lawless invasions of the constitutional rights of citizens’ ”, Terry v. Ohio,
. It would be absurd to suggest that the authorities could obtain a confession by torture and have evidence derived therefrom admissible at trial. The Court noted in Tucker, n. 23, at 2366: “Although completely voluntary confessions may, in many cases, advance the cause of justice and rehabilitation, coerced confessions, by their nature, cannot serve the same ends.”
. The court observed that it was unlikely that the body would have *152 been found without the aid of the accused. It was in a deeply wooded area removed from civilization and the police had no other evidence to connect the accused with the body other than his statements.
. Upon rehearing en banc, the opinion was modified. A majority of the court opined that the Agent had a right to ask about guns as a “minimally offensive security measure in the line of Terry v. Ohio,
