The United States appeals from an order of the United States District Court for the Southern District of New York (Harold Baer, Jr., Judge), suppressing physical evidence — principally social security cards bearing various numbers and names— seized in Defendant Romanus Isiofia’s apartment. The seizure by at least eight federal and New York City law enforcement officers occurred during a warrant-less home search after the agents, according to the District Court, encamped in the apartment for a lengthy period of time in furtherance of their investigation and apparently in anticipation of obtaining Isio-fia’s consent to the search. Following a hearing, the District Court concluded that the items were seized in violation of the Fourth Amendment. Because we conclude that the District Court did not clearly err in concluding that Isiofia’s consent was not voluntary, we affirm.
BACKGROUND
In March 2001, the Cole Computer Corporation, a computer vendor, was contacted by Modular Computers inquiring about the purchase of some $12,000 in computer parts. Modular subsequently faxed a purchase order to Cole, which provided four different credit card numbers and requested that the cost of the computer parts be split equally among the cards. A letter from a “Dennis Brown,” the “Director” of Modular, accompanied the purchase order and purported to authorize the purchase. Cole initially processed the order, but subsequently suspected that the transaction was fraudulent, canceled it, and contacted the U.S. Secret Service.
After an investigation, the Secret Service learned that the charges were unauthorized and that the four credit cards had been stolen. The Secret Service also learned that “Dennis Brown” of Modular had asked Cole to ship the computer parts to an individual named “Robert Heskey” at an apartment in the Bronx, New York, that subsequently was determined to be Isiofia’s address.
In an effort to identify and arrest the individual attempting to use the stolen credit card numbers, several law enforcement officers, including members of the Secret Service, the U.S. Postal Inspection Service, and the New York City Police Department, organized a controlled delivery of the computer parts. For reasons not apparent on the record, the agents did not apply for a search warrant or an anticipatory arrest warrant, although ample time to do so existed. On the morning of March 27, approximately six days after the parts were ordered, Postal Inspector Andre Esannason dressed as a mail carrier and, along with Special Agent Karen Fon-tana Graves of the Secret Service and Detective Tony Cruz of the NYPD, went to Isiofia’s apartment with the packaged com *229 puter parts. After Isiofia admitted them into the building, Esannason proceeded to Isiofia’s apartment door to deliver the package, while Graves and Cruz hid in a stairwell nearby awaiting the prearranged signal to move in and arrest whomever accepted delivery of the package as Robert Heskey.
When Esannason arrived at the apartment, the door was open and Isiofia was waiting in the doorway. Esannason informed Isiofia that he had a package for Robert Heskey and asked Isiofia if he were Heskey. Isiofia nodded affirmatively, but signed two different postal receipts with the name “T. Smith,” something Esannason did not realize until later. After Isiofia signed the postal receipts, Esan-nason gave the prearranged signal for Graves and Cruz to move in for the arrest. As they approached, Isiofia backed into his apartment. The agents followed Isiofia into the foyer of his apartment, where they arrested and handcuffed him. Cruz then radioed for assistance, and Esannason, Graves, and Cruz waited inside Isiofia’s apartment for the other officers to arrive. Moments later, five to seven law enforcement officers, including Special Agents William Guida and Brendan McGee, entered the apartment. At that point, Esan-nason informed Guida, the case agent, that Isiofia had signed the postal receipts with the name “T. Smith” rather than “Robert Heskey.”
Shortly after entering the apartment, Guida and McGee (with no weapons drawn) conducted a protective sweep which lasted approximately two minutes. After the protective sweep, McGee handcuffed Isiofia to a chair at a table near the entrance to the apartment. When he asked Isiofia his name, McGee had trouble understanding the response and consequently asked Isiofia for identification. Isiofia pointed toward a closed briefcase across the room. McGee asked if he could open the briefcase and retrieve the identification, and Isiofia answered affirmatively. Inside the briefcase, McGee found an identification card for Isiofia and removed it. He also saw several other social security cards with other names on them, but did not remove them at that time.
The officers then completed arrest-related paperwork, a task that took approximately thirty minutes. The detailed information the officers obtained from Isiofia included his name, residence, bank account information, ages and dates of birth of his children, the names and phone numbers of several relatives, his passport number, and his employment and social security numbers. Isiofia was under arrest at the time this information was assembled, and the record reflects that the agents claimed they completed the paperwork in his home, as opposed to a police station, out of convenience.
After the agents completed the paperwork, McGee read Miranda warnings to Isiofia from a waiver-of-rights form, and Isiofia executed a written waiver of those rights. Isiofia also signed a consent-to-search form, permitting Guida and McGee to search his apartment and car. On that form, the space for the nature of the contraband or evidence sought was left blank. A short while later, McGee filled out another consent-to-search form for Isiofia’s computer located in the apartment, which Isiofia also signed. On that form, the space for the names of the persons authorized to perform the search was left blank, but the nature of the contraband or evidence sought was identified as “crime/package delivery.” No separate consent form was executed for the search of Isiofia’s briefcase. After obtaining his signature on the two forms, the officers searched the briefcase, apartment, car, and computer. They found fifteen social secu *230 rity cards issued in the names of approximately eleven individuals. Among those fifteen cards were two in the name of Romanus Isiofia bearing different social security numbers.
In September 2002, a grand jury returned a four-count indictment charging Isiofia with (1) using a social security number assigned to him on the basis of false information to obtain payments or other benefits to which he was not entitled in violation of 42 U.S.C. § 408(a)(7)(A) and 18 U.S.C. § 2; (2) possessing a counterfeit resident alien card in violation of 18 U.S.C. §§ 2, 1546(a); (3) producing counterfeit resident alien and social security cards in violation of 18 U.S.C. §§ 2, 1028(a)(1), (b)(1)(A)®, (c)(1); and (4) possessing social security cards, a false social security card, a U.S. passport, and driver’s identification cards in the names of five or more individuals in violation of 18 U.S.C. §§ 2, 1028(a)(3), (b)(2)(B), (c)(1). Isiofia was not charged with purchasing the computer parts using stolen credit cards.
Isiofia moved to suppress the physical evidence seized from his apartment and a statement in which he told law enforcement officers his social security number. The District Court held a hearing at which Esannason, McGee, Graves, and Isiofia’s wife, Mercy Orji, testified. After the hearing, the Court suppressed the physical evidence, but not Isiofia’s statement.
United States v. Isiofia,
No. 02 CR. 520(HB),
DISCUSSION
On appeal, the government challenges both grounds for suppressing the physical evidence. First, it argues that neither the warrantless entry nor the sweep violated the Fourth Amendment, and that, in any event, Isiofia’s consents were sufficiently attenuated from the entry and the sweep to purge any taint resulting from them.
See Brown v. Illinois,
The government has the burden of proving, by a preponderance of the evidence, that a consent to search was volun
*231
tary.
United States v. Calvente,
The District Court, after weighing evidence adduced during a hearing heavily driven by credibility determinations, found that Isiofia’s consent was not voluntary. In so doing, the Court considered a number of factors. Among other things,
1
the Court considered the time that elapsed between Isiofia’s arrest and his consent. It found that Isiofia’s consent to open and search his briefcase was given only minutes after the initial entry by the agents, “close in time to what must have been a very startling, to say nothing of harrowing, series of events.”
Isiofia,
The government challenges this finding. First, it contends that there was nothing coercive about the length of Isiofia’s detention; the agents merely solicited pedigree information and in so doing neither coerced nor threatened Isiofia. The government further argues that the fact that Isiofia was not a native English speaker does not mean he was coerced, and that the agents and Isiofia had no trouble understanding each other. Second, the government argues that the District Court should not have considered whether Isiofia was informed of the crime he was being charged with or what evidence the government hoped to obtain during the search. Rather, the government maintains, the only factor relevant to the Court’s consideration was whether Isiofia had been informed of his right to refuse consent, and both consent-to-seareh forms signed by Isiofia expressly informed him of that right. Finally, the government contends that neither the entry nor the protective sweep were illegal, and, even if they were, Isiofia’s consents were sufficiently attenuated to purge the taint arising from them.
In addressing these contentions, it is important to remember that we review the District Court’s conclusions on the voluntariness of Isiofia’s consents for clear error.
See United States v. Puglisi,
We cannot say that the District Court’s conclusion on the voluntariness of Isiofia’s consent is clearly erroneous. The Court’s finding of coerciveness stemming from the length of Isiofia’s detention is grounded in the record. As the District Court noted, the evidence showed that Isiofia consented to the search of his apartment and car only after being handcuffed to a table for over thirty minutes in the presence of numerous law enforcement agents, some of whom extracted detailed personal and financial information from him. Although the officers testified that they neither threatened nor yelled at Isiofia, his affidavit testimony, which the District Court considered, tells a different story. In that sworn affidavit, Isiofia claims that the agents “demanded” his consent and told him “that if *233 [he] did not provide [his] consent, [he] would be jailed and deported and would never see [his] family again.” He also claims that the agents “yelled” at him using “abusive language.” Similarly, with respect to Isiofia’s facility with English, even though the government now claims that the agents and Isiofia had no trouble understanding one another, Special Agent McGee testified that upon asking Isiofia his name, he could not understand the response, which is the justification he offered for needing to search Isiofia’s briefcase for identification in the first place. Isiofia also offered evidence to this effect in his affidavit, which states that he “often ha[s] difficulty speaking and understanding” English. In light of all this evidence, we cannot say the government carried its burden of demonstrating that the District Court’s finding was clearly erroneous.
Nor is a contrary result compelled by the District Court’s belief that the agents neglected to tell Isiofia that he had a right to refuse consent.
See Isiofia,
The Court also considered the fact that the agents had not informed Isiofia of what type of evidence they expected to seize or the crime they expected to charge.
Isiofia,
Finally, even assuming
arguendo
that the officers’ warrantless entry and protective sweep were not illegal, we agree with the Court that the agents improperly remained in the apartment after completing the sweep.
Isiofia,
[o]nce police eliminate the dangers that justify a security sweep — safety of police, destruction of evidence, escape of criminals — they must, barring other exigencies, leave the residence. Were this not the rule, searches begun as minor intrusions on domestic privacy would expand beyond their legitimate purposes. This concern is particularly germane to government-citizen encounters where, as here, agents subsequently seek the resident’s consent to search his domicile.
United States v. Oguns,
CONCLUSION
For the foregoing reasons, the order of the District Court is affirmed.
Notes
. The parties disputed below whether Isiofia was intoxicated that morning. Isiofia did not testify at the suppression hearing, but submitted an affidavit stating that he is a recovering alcoholic and that he was “highly intoxicated” at the time he was arrested. Isiofia's wife testified at the suppression hearing, confirming that Isiofia is an alcoholic and stating that Isiofia had arrived home earlier that morning, at approximately 4:00 a.m., carrying two 40-ounce bottles of malt liquor, one of which he proceeded to open and drink while watching television. She testified that she then went to bed and awoke at 7:00 a.m. and that, upon leaving the apartment an hour later, she noticed Isiofia "sitting down drinking as usual.” The three law enforcement officers who testified at the hearing, however, stated that they detected no alcohol on Isiofia's breath and observed no other common signs of inebriation such as slurred speech, red eyes, dizziness, or incoherence. But they did concede to seeing an open and partially empty bottle of beer. The Court found that Isiofia "had been drinking that morning and although not perfectly lucid, was also capable of comprehending,” and it ultimately concluded that his state of intoxication was only a "minor factor on the voluntariness scale.”
Isiofia,
. The government neither contends that the agents informed Isiofia of his right to refuse consent to the initial briefcase search nor points to any other evidence establishing the voluntariness of Isiofia's consent to that search. We conclude, therefore, that it has not discharged its burden in this regard.
See Bustamonte,
. In any event, the District Court did not treat this factor as dispositive, but merely as one consideration in the totality of the circumstances.
