Defendant, Jeffrey Clinton Raines, appeals from his jury conviction for distribution of heroin in violation of 21 U.S.C. § 841(a)(1) (1970). He was sentenced to five years in prison and to a consecutive three-year special parole term pursuant to 21 U.S.C. § 841(b)(1) (1970). The sole contention raised by the defendant on this appeal is that the District Court 1 erred in refusing to suрpress a quantity of marked currency and the defendant’s incriminating admissions obtained by a government agent upon being invited into defendant’s home by a ruse of posing as a mutual friend of the defendant’s heroin distributee who had been arrested and had implicated the defendant earlier the same evening. We affirm.
On March 7,1975, an undercover аgent of the Minnesota Bureau of Criminal Apprehension who had been supplied with marked government currency, purchased three grams of heroin from James Pierce at Pierce’s residence in White Bear Lake, Minnesota, and immediately arrested Pierce. Pierce identified his source to be Michael Longville. Longville was promptly arrest *798 ed and the sum of $230 of the original $830 in marked currency was recovered in a search of Longville’s home. Thereafter, Longville identified his source to be the defendant, an acquaintance who worked at the same industrial plant. When Longville was interviewed by Agent John Boulger, a Minneapolis policeman assigned to the Federal Drug Enforcement Administration (DEA) Task Force, he admitted that earlier the same evening he had purchased the heroin from the defendant with some of the marked currency and had returned to the defendant two grams of heroin unsold.
At approximately 1:30 a. m. on March 8, after Pierce and Longville had been incarcerated, Agеnt Boulger went to Raines’ residence to investigate whether Raines possessed heroin and any of the marked currency. Raines was at home caring for his infant child while his wife was away attending a pregnant friend. Agent Boulger later testified during the suppression hearing, that while several officers were positioned nearby, he had persоnally knocked on Raines’ front door and posed as Long-ville’s friend, asking through the door whether Raines was acquainted with Long-ville. Raines answered that he was and Agent Boulger informed him that Longville had been arrested. Raines invited Agent Boulger inside and quickly asked what Longville had been arrested for. Agent Boulger told Raines the charge against Longville was possession of heroin, which information understandably appeared to unnerve Raines. Agent Boulger than revealed his official identity and told Raines he believed marked currency and heroin were on the premises. At this point, as many as four additional officers entered the house through the same door with weapons concealed.
Agent Boulger informed Raines that the house would be guarded and other officers would apply for, or try to obtain, a search warrant. Raines later testified that he was told the officers would obtain a warrant, not simply attempt to get one. Raines responded that there was no heroin on the premises but that the money was in the bedroom, and he turned tоward the bedroom to get it for them. Agent Boulger, however, paused to inform Raines that he need not surrender the money as the officers would apply for a search warrant. Raines proceeded to the bedroom with Agent Boulger and produced an envelope containing $800 from a dresser drawer. A check of serial numbеrs revealed that $550 of the currency was marked. Agent Boulger returned the balance and administered Miranda warnings to the defendant. Thereafter, when Raines was asked if he had any money in his pockets, he produced an additional $50 in marked currency that accounted for all the $830 originally disbursed. The defendant also admitted that Longville had givеn him the marked currency along with two grams of unsold heroin but Raines claimed he had returned the heroin to his source. He also admitted that he had been dealing in heroin for two months, but refused to identify his source because of fear for his personal safety. The agents then departed, allowing him to turn himself in to the police the next day without еscort. Raines later denied making the admissions and claimed he never dealt in heroin.
On this appeal, the defendant contends that all evidence procured in his home must be suppressed as the fruit of an unlawful police entry. He argues that the ruse employed by Agent Boulger to coax an invitation inside was an unreasonable intrusiоn prohibited by the Fourth Amendment and that Agent Boulger and the other officers failed to observe the common law obligation of a government agent, codified in 18 U.S.C. § 3109 (1970), 2 to announce his iden *799 tity and purpose before breaking into a private home. Secondly, the defendant contends that the agents’ intrusion into his home under the circumstances coerced him intо incriminating himself and consenting to a warrantless search in violation of his rights under the Fourth and Fifth Amendments. The District Court, after an evidentiary hearing, rejected these claims. Agent Boulger’s invited entry into the defendant’s home, though obtained by ruse, was not unlawful. The officers’ acquiescence thereafter in the defendant’s spontaneous surrender оf inculpatory evidence was not a search or seizure and the defendant’s voluntary admissions were not coerced. 3
I. UNLAWFUL ENTRY.
The defendant contends that Agent Boulger’s entry by ruse into his home was improper, that all evidence procured thereby was tainted and that it must be suppressed under
Wong Sun v. United States,
The difference, he maintains, is that Agent Boulger’s announced purpose for appearing at the door, and the defendant’s purpose for inviting him inside, were entirely lawful. They sought to discuss the fate of a mutual friend. In Lewis, however, the mutual purpose shared by the defendant and the undercover agent was to consummate an illegal sale of nаrcotics. The Government responds that Agent Boulger’s ruse was not unrelated to the defendant’s criminal conduct. Agent Boulger represented himself to be a mutual friend of one of the defendant’s drug associates and truthfully told the defendant that the associate had been arrested. The defendant promptly invited the agent inside, apparently to learn whether the arrest was related to his narcotics dealing.
In our view, the defendant’s attempt to distinguish between types of deception is without substance. Though the Supreme Court of the United States has not had occasion to decide a similar case,
4
we are of
*800
the view that Agent Boulger’s entry by consent, though obtained by ruse, did not intеrfere with the defendant’s Fourth Amendment rights and did not taint the evidence procured thereafter in the defendant’s home.
United States v. Syler,
[A]n officer may legitimately obtain an invitation into a house by misrepresenting his identity * * *. If he is invited inside, he does not need probable cause to enter, he does not need a warrant, and, quite obviously, he does not need to announce his authority and purpose. Once inside the house, he cannot exceed the scope of his invitation by ransacking the house generally, * * * but he may seize anything in plain view.
If an entry by ruse would not prevent an officer from carrying out a plain view search, it follows that he may engage in other police activity, such as that undertaken in the instant case, but otherwise prohibited where he is entitled to be.
The defendant’s reliance upon
Gouled v. United States,
Further, Agent Boulger’s failure to announce his authority and purpose before entering the defendant’s home did not violate 18 U.S.C. § 3109.
United States v. Beale,
II. UNLAWFUL COERCION FOLLOWING THE ENTRY.
The defendаnt contends that the marked currency and incriminating admissions procured by the government agents upon entering his home must be suppressed on two additional grounds. He argues that he was unlawfully induced to consent to a search and coerced into incriminating himself in violation of his rights under the Fourth and Fifth Amendments. However, neither argument is supported by the record nor requires extensive discussion.
Defendant’s first contention is that Agent Boulger’s comment that the officers would guard the house and apply for a search warrant was an unjustified coercive threat that a warrant would be in fact be obtained when, he argues, the officers lacked probable cause to obtain а search warrant. Thus, the defendant maintains that under the circumstances he was induced to consent to a search in violation of his Fourth Amendment rights. However, the argument rests upon a twofold misconception of the facts. The testimony adduced in the suppression hearing reveals that Agent Boulger did not threaten to obtain a search warrant; he merely stated that a warrant would be applied for and that Raines need not produce the marked currency without one. The agent’s assertion under the circumstances was not impermissibly coercive,
see United States v. Culp,
The Fourth Amendment protects only against unreasonable searches and seizures; it does not prohibit the police from acquiescing, as here, in a defendant’s spontaneous, uncoerced offer to incriminate himself by supplying physical evidence and admitting participation in crime. Here, the agents lawfully, though by ruse, entered the defendant’s home and, once inside, witnessed the defendant’s voluntary relinquishment of incriminating evidence. No probable cause or formal consent is required in addition to enable the Government to use the evidence against the accused at trial. To hold otherwise would permit a suspect to frustrate police investigation by quickly surrendering incriminating еvidence before government agents are able to secure a search warrant, administer Miranda warnings or conduct a search.
Finally, the defendant contends that as soon as Agent Boulger revealed his identity, the initial conversation was transformed *802 into improper custodial interrogation and that all evidence procured before the defendant reсeived Miranda warnings must be suppressed. Moreover, the defendant contends that even the inculpatory admissions made by him following the administration of Miranda warnings must be suppressed as they were coerced under the circumstances in violation of his Fifth Amendment privilege against compelled self-incrimination.
We find no merit in these contentions. Even if we assume, without deciding, that thе defendant was in custody at the time he volunteered the marked currency,
8
the record reveals that he was not interrogated prior to receiving
Miranda
warnings, and that after receiving the warnings he freely and voluntarily responded to questions and admitted participation in the crime. The Fifth Amendment does not bar the use of physical evidence or admissions volunteered by a defendant without interrogation or “compelling influence.”
Miranda v. Arizona,
The judgment of conviction is affirmed.
Notes
. The Honorable Edward J. Devitt, Chief Judge, United States District Court for the District of Minnesota.
. The statute provides:
Breaking doors or windows for entry or exit
The officer may break open any outer or inner dоor or window of a house, or any part of a house, or anything therein, to execute a search warrant, if, after notice of his authority and purpose, he is refused admittance or when necessary to liberate himself or a person aiding him in the execution of the warrant.
In
Miller v. United States,
. The defendant’s contention that the agents, upon entering his home, lacked probable cause to arrest him without a warrant or to obtain an arrest warrant bеfore entering, is not well taken. He cannot seriously contend that Agent Boulger, having interviewed Michael Longville the same evening, lacked an articulable and objective basis for reasonable suspicion that criminal conduct was afoot in the defendant’s home, leading him to investigate further by going there.
See Adams v. Williams,
. In
Sabbath v. United States,
Similarly, in
United States v. Hutchinson,
. In
Gouled,
a business acquaintance of the defendant, acting under orders of federal officers, obtained entry into the defendant’s office by falsely representing that he wished to pay a social visit; but in the defendant’s absence, he secretly searched the office and seized incriminating private papers. The Court held the general ransacking in the defendant’s absence to be a Fourth Amendment violation.

Schneckloth v. Bustamonte,
. Although the subsequent entry of other government agents in addition to Agent Boulger could have increased the defendant’s anxiety, our review of the record does not reveal unduly coercive circumstаnces. Rather, the testimony in the suppression hearing, including that of the preliminary hearing incorporated into the suppression hearing by stipulation, suggests that the encounter was relatively cordial and informal. The District Court’s implicit determination that no unlawful coercion occurred, based upon the testimony and assessment of credibility, is supported by substantial evidence and will not be disturbed.
Mullins v. United States,
. Though the defendant had not been informed that he was under formal arrest when he produced the currency, Agent Boulger later testified that the defendant would not have been permitted to leave the house if he had attempted to do so. However, he was not taken to the police station that night. He was permitted to surrender to the police voluntarily the following day.
