Defendant was indicted on three counts of violation of section 11500 of the Health and Safety Code. Count I charged a sale of heroin on December 14, 1955; Count II charged a sale of heroin on January 19, 1956, and Count III charged possession of heroin on January 19, 1956. It was alleged that defendant had previously suffered three convictions, one for burglary and two for violations of section 11500. Defendant’s motion to set aside the indictment was denied. Defendant initially pleaded not guilty to all counts and previous convictions. Before selection of a jury, defendant admitted the prior convictions. Defendant was found guilty on all three counts.
The defendant has alleged seven grounds of appeal. They are (1) the court erred in admitting testimony of an officer concerning a telephone conversation between defendant and an informer which was overheard by means of an amplifier and extension cord; (2) that the arrest without a warrant was illegal; (3) that the search and seizure without a warrant was unlawful and within the exclusionary rule of the Cahan *439 case; (4) that the court erred in not submitting the question of the reasonableness of the arrest and the legality of the search and seizure to the jury; (5) the court committed error in not requiring the officers to disclose the name of the informant during the voir dire examination; (6) the court erred in not requiring the officers to disclose the namе of the informant at the trial before the jury; (7) it was error for the court to refuse to allow a witness produced by defendant, whom he alleged to be the informant, to testify. The numerous grounds of appeal require a rather detailed statement of the facts to provide proper background for a discussion of each question presented.
The Pacts
Inspector George Olsen testified that he was present in the State Building on December 14, 1955, when a known informant placed a telephone call to Evergreen 6-5633. The party at the other end said, “Hello.” The informant asked, “Hello, is this you, Jesse?” The other party said, “Yes.” The informant said, “Is anything happening?” The other party said, “Yes.” The infоrmant said, “Can I get anything?” The other party said, “Yes, come on over.” Inspector Olsen identified Jesse Lawrence as the recipient of the call, and recognized him by his voice. The informant was searched, his clothes removed, all pockets searched, and the linings removed from his trousers. Inspector Olsen, Inspector Noel and the informant proceeded to Spruce and Sacramento Streets where the informant was handed $200 in identified State funds. Then the inspector observed the informant walk directly to a green 1951 Packard, in which defendant was sitting behind the wheel. The informant and defendant conversed for approximately two minutes. Then, they went into 451 Spruce Street. Approximately one and one-half hours later defendant, his wife and the informer came out of 451 Spruce Street. Defendant and his wife got in their car. The informer headed north on Spruce. The informer met Inspectors Noel and Olsen at Sacramento and Spruce, and there surrendered to Inspector Noel a rubber container in which there was a white powder later identified as 210 grains of heroin. The inspectors returned the informant to the State Building. They searched him and found none of the money.
Inspector Louis Noel testified that he was present in a public telephone booth at Washington and Broderick Streets on January 19, 1956, when the informant called Evergreen *440 6-5633. Noеl dialed the number. He monitored the conversation through an amplifier which he placed over “the listening end” of the receiver. The informant said, “Hello, is that you, Jesse?” The other party replied, “Yes.” The informant asked, “Can I get anything?” The other party said, “Yes, come on by.” Officer Noel identified the other party as Jesse Lawrence, the defendant. Then the informant was taken to a State vehicle and searched. No contraband was found. He was given $206 in marked state-identified bills. The informant and several officers proceeded to the vicinity of Sacramento and Spruce Streets. The informant went to 451 Spruce, in a building containing three flats. He went up the stairs to the doоr at 451 and stood for a moment or two. Defendant raised a window facing on Sacramento Street. The two men apparently conversed for a short while. The informant descended the stairs and defendant dropped what appeared to be a key down to the informant. The informant picked up the key, went up to the doorway at 451 Spruce, opened the door and went in. Over an hour later, the informer came out of 451 Spruce Street. He entered a blue-colored taxicab which proceeded toward California Street. Noel contacted other state officers by radio and informed them of the direction the taxi was proceeding.
Officer Rinkеn testified that on January 19, 1956, he was in contact with Inspector Noel from the time the informer went into 451 Spruce Street. Sometime later, he was advised to look for the informant in a taxicab. He spotted bim in a blue DeSoto cab near Spruce and California Streets. He followed the informer to the intersection of Euclid, where he got out of the taxicab and gave Rinken a rubber contraceptive containing a white powder which was identified as 190 grains of heroin.
Inspector Noel testified that after the informant left the defendant’s premises he observed Gerald Williams and defendant’s wife, Norvelle Lawrence, leave 451 Spruce Street. Noel radioed Officer Rinken to take Williams into custody. Noel searched Williams and found neither narcotics nor any of the marked bills given to the informer. The officers had Williams return with them to 451 Spruce and ring the door bell. Defendant opened the door. The officers identified themselves and announced that defendant was under arrest for sale of narcotics. Defendant tried to close the door and it was necessary to forcibly take him into custody. Inspector *441 Noel testified that after subduing defendant, he proceeded up the stairs, where he was met by Inspector Chasten, who showed him a container full of white powder which contained 291 grains of heroin. Noel found a white paper containing one grain of heroin on a cocktail table, and $170 of the money which had been given to the informer in a small cardboard box on a dresser next to defendant’s bed. Defendant admitted that it was his money, and said he gambled. Defendant admitted that the container which Inspector Chasten had given to Noel was his, and that he used it for his asthma. Noel observed that the number of the telephone was Evergreen 6-5633.
Objection was sustained to questions by defense counsel seeking to elicit the name of the informant. Defendant then produced Willie Dandridge, an inmate at San Quentin prison, and alleged he was the informant. Dandridge was permitted to testify on voir dire and admitted that he was at defendant’s house but was uncertain as to the date. He admitted that defendant threw a key out of the window to him; that he left defendant’s premises in a blue DeSoto cab; he denied that he gave money to or purchased narcotics from the defendant. He denied he gave a package of narcotics to Inspector Noel on December 14, 1955, or to Officer Rinken on January 19, 1956. He denied he had informed officer Noel or any other state officer that narcotics could be or had been purchased from defendant. On cross-examination Dandridge denied that he had ever been in the State Building or had agreed to help Inspector Noel. Dandridge did admit that Gerald Williams was at defendаnt’s apartment the day he was there. The defendant asked to call Willie Dandridge as his witness at the trial before the jury but the district attorney objected and the court sustained the objection. The defendant testified on his own behalf and categorically denied any and all sales of narcotics. He denied any telephone conversations with the informant and he testified that the officers threatened him and actually used force on his person unnecessarily at the time of the arrest. Gerald Williams corroborated the defendant’s testimony as to most of the events transpiring on January 19, 1956.
Admissibility of Telephone Conversation.
Defendant charges the court erred in permitting an officer to relate a telephоne conversation between the defendant and an informant. The officer listened to the conversation
*442
by means of an amplifier attached to the receiver and an extension cord. Defendant contends “the listening-in” by the officer was an invasion of defendant’s right of privacy guaranteed by the Constitution of the United States, by article I, section 19 of the California Constitution, and that it was a violation of Penal Code, section 640. The identical question was presented in the case of
People
v.
Malotte,
“Defendant contends, however, that the evidence was obtained in violation of the Federal Communications Act (47 U.S.C.A. § 605), and section 640 of the California Penal Code and that it was, therefore, inadmissible under the rule of People v. Cahan,44 Cal.2d 434 [282 P.2d 905 ].
“Section 605 of the Federal Communications Act provides: ‘... no person not being authorized by the sender shall intercept any communication and divulge or publish the existence, contents, substance, purport, effect or meaning of such intercepted communication to any person; . . .’ A majority of the federal courts define ‘intercept’ as used in section 605 to mean ‘to take or seize by the way, or before arrival at the destined place, ’ and hold that there is no interception when the intended receiver consents to or directs the overhearing of the communication at the moment it reaches him. [Citations.] The United States Supreme Court, approving this definition in the Goldman case, supra,316 U.S. 129 , 134 [62 S.Ct. 993 ,86 L.Ed. 1322 ], went on to say: ‘ [Intercept] does not ordinarily connote the obtaining of what is to be sent before, or at the moment, it leaves the possession of the proposed sender, or after, or at the moment it comes into the possession of the intended receiver. ’ (See Reitmeister v. Reitmeister,162 F.2d 691 ). Thus, as in the present case, where the conversation was recorded by the officers ‘at the moment’ it reached the ‘intended receiver, ’ therе was no interception within the meaning of section 605 of the Federal Communications Act. There was likewise no invasion of privacy in violation of section 640 of the Penal Code. There is no learning of the contents of a communication ‘fraudulently, clandestinely, or in any other unauthorized manner’ when one of the participants to the conversation consents to or directs its overhearing or preservation. (See, People v. Channel,107 Cal.App.2d 192 , 200 [236 P.2d 654 ].)”
*443 The instant ease clearly comes within the rationale of the Malotte ease and the trial court properly permitted the officer to relate the conversation.
The Arrest and Search and Seizure.
Defendant contends that the trial court erred in not excluding all evidеnce seized by the officers in his apartment because the officers had no search warrant. The defendant being well aware of the rule that a search without a warrant may be incidental to a lawful arrest regardless of whether the search is made before or after the arrest
(People
v.
Simon,
Penal Code, section 836, provides that a peace officer may without a warrant arrest a person “when a felony has in fact been committed, and he has reasonable cause for believing the person arrested to have committed it. ’ ’ Reasonable cause is shown when under the state of facts of the particular case a man of ordinary care and prudence, knowing what the arresting officer knows, would believe or entertain a strong suspicion that the person is guilty.
(People
v.
Kilvington,
The arrest was lawful and the search incidental thereto was also lawful, even though made without a search warrant, whether the search preceded or followed the arrest.
(People
v.
Simon,
Defendant argues even though the arrest was lawful, it was made in the entry hall to defendant’s apartment and the officers had no right to search the apartment. This position is untenable. The marked money with which thе informant purchased the heroin just prior to the arrest was a natural object of the search. It was a part of the res gestae, and the search of defendant’s apartment to find it was incidental to the arrest and entirely reasonable. In any event in making a search incidental to a lawful arrest an officer is not restricted to the area immediately surrounding the location of the defendant at the time he is arrested. The law contemplates a reasonable search of the vicinity. In
United States
v.
Pisano,
“. . . Searches and seizures incidental to an arrest but without search warrants are not necessarily unreasonable but are, in the absence of unusual circumstances, entirely reasonable. The right to search the place where the arrest is made and to find and seize things connected with the crime as its fruits or as the means by which it is committed stems not only from the authority to search the person but also from the long standing practice of searching for other proofs of guilt within the control of the accused upon arrest. (Citation.) Consequently the premises where a valid arrest is made, under the control of the person arrested, are subject to search without a search warrant. Such a search is not unreasonable. (Citation.) The only essential of validity of a search incidental to an arrest is that it be made in connection with a valid arrest. If thе arrest is valid then a search of the immediate premises where the defendant is arrested is reasonable. The decisive question is not whether a search warrant could have been procured but whether the search made was reasonable and that, in turn, in the absence *446 of exceptional circumstances, depends upon whether the arrest was valid.”
(See also
Carroll
v.
United States,
The fact the officers gained admittance to the entry hall by subterfuge in order to make the arrest is immaterial. The officers had reasonable cause to believe defendant had committed a felony and the fact that they resorted to trickery to get the door to defendant’s apartment open in order to arrest him has no bearing upon the justification for the arrest.
(People
v.
Sayles,
Submitting Question of Reasonableness of Arrest and Search and Seizure to the Jury.
Defendant argues that the evidence concerning the reasonableness or legality of the arrest and seizure should have been presented to the jury on the trial of defendant’s guilt. Defendant does not dispute the advisability of the court determining the reasonableness of the arrest and search and seizure outside the presence of the jury in the first instance. His position is that when the court determines that the arrest and the search and seizure were lawful, the cоurt is then determining a question of fact. He contends the question of fact and the evidence from which it was determined should then be presented to the jury for its determination in the trial proper. Defendant bases his argument on the procedure established to determine the admissibility
*447
of a confession. Even though the court determines its admissibility the jury ultimately passes upon the question of whether or not the confession was given voluntarily. This question was decided by the Supreme Court in
People
v.
Gorg,
“Defendant urges, however, that the same procedure should be followed as in the ease of a confession, where the trial court initially determines the question of admissibility and then instructs the jury to disregard the confession if they find thаt it was not freely and voluntarily made. The rule of the confession cases is justified by the fact that the jury must necessarily be informed of the circumstances surrounding the confession properly to evaluate it. The probative value of evidence obtained by a search or seizure, however, does not depend on whether the search or seizure was legal or illegal, and no purpose would be served by having the jury make a second determination of that issue. Moreover, the legality of a search or seizure will frequently depend on whether the officer had reasonable cause to make an arrest, and since such cause is not limited to evidence that would bе admissible at the trial of the issue of guilt (People v. Boyles, ante, p. 652 [290 P.2d 535 ], and cases cited), evidence that was otherwise inadmissible and prejudicial would frequently be presented to them if the jury were required to pass on the legality of the search or seizure.”
The Gorg case prescribes the procedure to determine the admissibility of evidence when the question of reasonableness or legality of an arrest or search or seizure becomes an issue. The reasons given for adopting the procedure are unassailable.
Disclosure of the Name of Informant-Participant.
During the voir dire examination to determine the legality of the arrest and the search and seizure, defense counsel, upon the cross-examination of one of the officers, аsked whether or not the same informant made the purchases on December 14th (Count I) and January 19th (Count II) and the officer answered, “Yes.” Defense counsel then asked the informant’s name and the district attorney objected upon the ground the name of an informant is confidential information. The court sustained the objection. Defense counsel then asked the witness to describe the informant. The district attorney objected upon the same ground. The court sustained the objection. The defendant then produced one Willie Dandridge, an inmate of San Quentin prison and *448 stated that Dandridge was the informant. Dandridge was placed on the witness stand by defendant and testified he had been with the оfficers in January; that he had been in the defendant’s apartment but that he had never purchased any narcotics from the defendant. He denied making any telephone calls to the defendant and he denied he had ever told the officers he had purchased narcotics from the defendant. The court disbelieved Willie Dandridge and the defendant, and ruled there had been probable cause for the arrest and that the search and seizure made incidental thereto were lawful. The trial then continued in the presence of the jury. Again, the officers testified that an informant had made the purchases on December 14th and January 19th and telephone calls on December 14th and January 19th. They again described the procedure followed in preparing the informant to make the purchases and identified the narcotics delivered to them by the informant on December 14th and January 19th. Upon his cross-examination of the officers during the trial before the jury defense counsel again asked the officers the name of the informant who made the purchases. The district attorney objected upon the ground that it was confidential information and the court sustained the objection. Upon the completion of the People’s case defense counsel called the witness Willie Dandridge. The district attorney objected to Dandridge testifying and moved the court for an order requiring defense counsel to make an offer of proof concerning the testimony of Willie Dandridge and to make the offer in the absence of the jury. The court granted the motion and the offer of proof was made in chambers. In substance, the offer of proof was that he would testify that he was the informant referred to by the officers in their testimony; that he did not purchase any narcotics from defendant on December 14th; that he did not make a telephone call to defendant on January 19th; that he was at defendant’s apartment on January 19th but did not purchase any narcotics from defendant on that day. Generally, the offer of proof followed the testimony which Willie Dandridge had given at the voir dire examination earlier in the trial. He contradicted the testimony of the officers on most material points. After defense counsel made his offer of proof, the district attorney again objected to Willie Dandridge being called as a witness for defendant and the court sustained the objection. Later during the trial a witness who was present in defendant’s apartment on January 19th testified *449 that Willie Dandridge was also present. Defense counsel then renewed his motion to call Willie Dandridge as a witness on defendant’s behalf. The district attorney objected and the court sustained the objection.
Counsel for appellant and resрondent agree that there is no California decision determining whether or not the name of an informant who participates in the criminal action with which a defendant is charged comes within the purview of Code of Civil Procedure, section 1881, subdivision 5, which provides:
“A public officer cannot be examined as to a communication made to him in official confidence when the public interest would suffer from the disclosure.”
The case of
People
v.
Lazzara,
The trial before the jury on the question of defendant’s guilt presents a different situation. The court not only sustained the prosecution’s objections to defense counsel’s questions concerning the name and identity of the informant, but when the defendant called Willie Dandridge as a witness and made an offer of proof, the court would not permit Willie Dandridge to testify. The offer of proof as well as Dandridge’s testimony on voir dire was in conflict with the testimony given by the officers on many material points. The trial court erred by sustaining the district attorney’s objections and in refusing to permit Dandridge to testify because it denied *450 the defendant the right to produce witnesses on his behalf and defend himself as guaranteed by article I, section 13 of the California Constitution and by Penal Code, section 686, subdivision 3.
The primary question presented, however, is whether or not an officer may withhold the name of an informer as a confidential communication even though the informant is a participant in the crime charged. The question presents a conflict between two fundamental principles of justice. The name of an informant who cooperates with law enforcement officers has been held to be confidential upon the theory the informant pеrforms a public service. He provides information which law enforcement officers are frequently unable to obtain by any other means. This is particularly true in narcotics cases. His service and his benefit to the public welfare would cease if his identity were disclosed. The courts have held this to be sufficient cause to protect the anonymity of the informant.
(People
v.
Gonzales,
“When it comes, however, to the point mainly and most vigorously argued, that it was errоr to deny the defendant’s request for the name of the informer to whom it was claimed the defendant had sold the narcotics, we are in no doubt that the appellant has the right of it. In
Sorrentino
v.
United States,
9th Cir.,
If the prosecution is not required to divulge the name of the buyer when a defendant is charged with a sale of narcotics on the ground it is confidential information, the way is left open for the “phantom” purchaser. The possibility is remote but the fact that the possibility exists at all when it can be eliminated violates the American concept of justice in a criminal trial.
We believe the same principle applies to a hearing on voir dire held out of the presence of the jury. Although the question of the guilt of the defendant is not before the court, nevertheless, the defendant has the same right to present his defense at the hearing to determine the reasonableness of an arrest or search as he does on the question of his guilt. The fact that the hearing is held before the court in the absence of the jury makes it no less a criminal proceeding. Due process applies and all the rights the defendant may have at the trial proper apply with equal force and dignity to the proceedings before the court sitting in the absence of a jury.
*452 When an informant becomes a participant in the crime charged against the defendant, he and the people lоse the right to keep his identity anonymous.
Error Affecting Count Three.
Respondent contends that if there was error in the court’s refusal to permit defense counsel to ask the officers the name of the informant-participant on cross-examination and to call Willie Dandridge to the witness stand to testify on defendant’s behalf, such error goes only to counts 1 and 2, but not count 3. It is true counts 1 and 2 are based upon sales to the informant while count 3 is one of possession of narcotics, a crime in which the informant did not participate. Nevertheless, all three counts were tried together, the officers who testified regarding counts 1 and 2 were also the principal witnesses concerning count 3. Willie Dandridge on voir dire contradicted the testimony of the officers on most material points. The jury did not hear him testify but had he been permitted to testify and had the jury or any juror believed him, it would have impeached the testimony of the officers. What effect that impeachment would have had it is impossible to say, but if believed, it would have affected the credibility of the officers as to their testimony concerning count 3. Thus, when the court erred in refusing to permit Willie Dandridge to testify on defendant’s behalf, it cannot be said the error was not prejudicial as to count 3.
Judgment is reversed as to all three counts.
Kaufman, P. J., and Dooling, J., concurred.
Respondent’s petition for a hearing by the Supreme Court was denied May 22, 1957. Shenk, J., and Spence, J., were of the opinion that the petition should be granted.
