The government appeals from an Order entered November 20, 2009, in the United States District Court for the Southern District of New York (Jones, J.), suppressing as evidence a handgun allegedly belonging to defendant-appellee Eric Hassock, a/k/a David St. Walton, a/k/a Basil LNU (“Hassock”). The government proposed to enter the firearm into evidence as proof of a fact material in the prosecution of Hassock for being a felon in possession of a firearm. The District Court determined, after a hearing, that the firearm was secured as the result of an unreasonable search of Hassock’s bedroom. The government contends on appeal, as it did below, that the handgun in question was discovered in the course of a proper protective sweep. We affirm for the reasons set forth below.
BACKGROUND
I. Investigation
In reciting the background for our analysis in this case, we rely essentially on the factual findings made by the District Court.
The investigation that led to Hassock’s indictment for being a felon in possession of a firearm began with information received from a confidential source. The information was supplied to Senior Special *81 Agent Christopher Quinn (“Agent Quinn” or “Quinn”) of the Department of Homeland Security, Immigration and Customs Enforcement (“ICE”) in November 2008. Agent Quinn identified the confidential source as “CS-1” in a complaint filed on January 22, 2009, in support of an arrest warrant for Hassock. In the complaint, Agent Quinn stated
that CS-1 saw BASIL LNU, a/k/a “David St. Walton,” the defendant, with a black semiautomatic handgun in BASIL LNU’s home, which is located in the basement apartment at 3201 Mickle Avenue in the Bronx, New York. CS-1 identified the building to me and other law enforcement agents and described the layout of the basement apartment. CS-1 further stated that BASIL LNU is a marijuana dealer. CS-1 also provided me with a picture of BASIL LNU. CS-1 further stated that CS-1 believes BASIL LNU is an illegal alien and is from Jamaica.
The investigation was pursued by an inter-agency task force (the “Task Force”) that included Agent Quinn and law enforcement personnel detailed from the Drug Enforcement Administration, the Federal Bureau of Investigation, the New York Police Department, the New York State Police, and the Internal Revenue Service. In the course of the investigation, the Task Force acquired information that “Basil” occupied the front bedroom in the basement apartment in which he resided; that he stayed out late, slept late, usually departed from his apartment around noon, and had no known legal employment. Moreover, the photograph and physical description provided to Quinn by the confidential informant showed Basil to be an African-American male approximately six feet tall and weighing approximately 220 pounds.
In order to obtain the true identity of “Basil,” which was then unknown, the Task Force conducted residence checks and record checks. These efforts were unsuccessful, and the Task Force resolved to speak with the subject of their investigation at his home. Accordingly, on November 25, 2008, Agent Quinn and four other Task Force members headed to the basement apartment at 3201 Mickle Avenue. The purpose of the visit, according to Quinn, was to conduct surveillance and to “knock and talk,” that is to “knock on the door and interview potential residents to see if the information that we have is accurate, to see if there is any further follow-up investigation we can do.” Tr. at 15. More specifically, Agent Quinn described the “initial reason” for the visit as an opportunity to talk to “Basil” and “another reason” as “to potentially arrest him.” Id.
II. Surveillance and Entry
When Agent Quinn and the other members of the Task Force arrived at 3201 Mickle Avenue on November 25 at approximately 8:00 a.m., they took up surveillance from their vehicle outside the building. After about an hour, during which no one was seen entering or leaving the basement apartment, the Task Force made the decision to pursue their investigation by simultaneously knocking on the front and rear doors of the apartment. On cross-examination at the suppression hearing, Quinn agreed that “[t]he purpose of knocking on the door[s] was to have this conversation with a person whom [he] believed was known as Basil.” Id. at 18.
Agent Quinn and two other members of the Task Force knocked on the front door, and two members knocked on the rear door after entering the fenced-in area of the yard. Those at the front door received no response after knocking for about a minute, but Quinn then received word by *82 radio from those at the rear that the door there was being opened. Quinn then walked to the rear of the building and there found a woman inside the apartment speaking to members of the Task Force.
At that point, according to Quinn, “[t]here was a brief exchange about who’s here. The young lady said, essentially, I don’t know, you g-uys woke me up. Is anyone else in the apartment, words back and forth like that. Can we look around? And she said yes.” Id. at 6. Quinn did not recall whether he overheard this conversation or whether it was repeated to him by another member of the Task Force. In any event, Quinn himself had no conversation with the woman who opened the door, nor did he or any other Task Force member ascertain her identity or question her further before proceeding into the interior of the apartment.
III. “Sweep, ” Discovery, and Seizure
In what the government described as a protective sweep, Quinn and another member of the Task Force, Detective John Salvetti (“Detective Salvetti”), passed through the apartment directly to the front where a bedroom was located. Quinn believed that this bedroom was occupied by “Basil,” whose true identify still was unknown to him. In approaching the bedroom, Quinn had his gun drawn (or had his hand on his gun), being concerned that Basil “could come out with a firearm or a gun or pose a danger.” Id. at 24. The bedroom, measuring approximately ten feet by ten feet, was one of two bedrooms in what Quinn described as a “pretty small” apartment, which included a living room, kitchen, and a common or storage area. Id. at 22.
The front bedroom was taken up for the most part by a queen-sized bed on a frame. Once inside the bedroom, Detective Salvetti walked around the bed, and Quinn squatted down to look under the bed. Underneath the bed, and six to eight inches from the edge of the bed, Quinn discovered a Hi-Point .380 caliber pistol with a defaced serial number. It is this pistol that forms the basis of the firearm count with which Hassock was charged. Members of the Task Force also looked around the common area and underneath and behind a sofa. They remained in the apartment for a couple of hours. During that time, they spoke in some depth with the woman who had answered the door. They then learned that her name was Shareel Coley, that she was employed at Nordstrom in White Plains, that she occupied the back bedroom with her boyfriend, that the front apartment was occupied by “Bas” or “Basil” whose full name was unknown to her, and that she had been staying in the apartment for approximately one month. Apparently, the officers later learned from other sources that the person known as “Basil” is Eric Hassock and is also known as David St. Walton.
IV. Proceedings in the District Court
An indictment filed on March 13, 2009, in the Southern District of New York charged that Hassock,
being an alien, unlawfully, willfully, and knowingly, did enter and was found in the United States, after having been deported from the United States on or about September 1, 2004, subsequent to a conviction for the commission of a felony, to wit, a conviction on or about April 6, 2000, in New York State County Court, Nassau County, for Criminal Possession of Marijuana in the Second Degree, in violation of New York Penal Law 221.25, without having obtained the express consent of the Attorney General of the United States or his successor, the Secretary for the Department of *83 Homeland Security, to reapply for admission.
(Title 8, United States Code, Sections 1326(a) & (b)(1).)
The indictment also charged that Hassock unlawfully, willfully, and knowingly, after having been convicted in a court of a crime punishable by imprisonment exceeding one year, to wit, a conviction on or about April 6, 2000, in New York State County Court, Nassau County, for Criminal Possession of Marijuana in the Second Degree, in violation of New York Penal Law 221.25, did possess in and affecting commerce, a loaded firearm, to wit, a .380 caliber Highpoint Semiautomatic handgun, with a defaced serial number, which previously had been shipped and transported in interstate and foreign commerce.
(Title 18, United States Code, Section 922(g)(1).)
By motion filed on June 9, 2009, Hassock sought to suppress from the evidence to be introduced at trial the firearm seized from his bedroom, contending it was discovered as the result of an illegal search. In support of his motion, Hassock filed his own affidavit, an affirmation by his attorney, and a memorandum of law. On June 18, 2009, the government filed a memorandum of law in opposition to the motion, contending that the firearm was seized during a lawful protective sweep. The District Court scheduled a hearing on the motion for June 26, 2009. The hearing was conducted on that date, and Agent Quinn was the only witness to testify. The court also heard the oral arguments of counsel, reserved decision at the conclusion of the hearing, and issued its Opinion and Order granting the motion on November 20, 2009.
In finding that the search of Hassock’s bedroom was unreasonable, the court carefully considered the government’s contention that the entry into Hassock’s bedroom was justified by the protective sweep doctrine first described by the Supreme Court in
Maryland v. Buie,
In the case at bar, the District Court determined “that the search was supported by a reasonable suspicion of danger and it did not exceed the scope of a protective sweep, [and that] the Court must decide whether the protective sweep doctrine applies in this context.” Id. at 159. In concluding that the protective sweep doctrine did not apply “in this context,” and granting suppression of the seized handgun, the court opined as follows:
In all, a protective sweep may be reasonable, and therefore constitutional, where officers enter a suspect’s home in order to execute a warrant, to enforce an order of protection, or pursuant to exigent circumstances. And there may be circumstances where police enter by consent and truly emergent conditions then arise. Here, however, by making a voluntary decision to enter the Apartment at approximately 9:00 AM on November 25, 2008, the task force put *84 themselves at risk of the very danger that necessitated the protective sweep. And nothing the officers learned upon entering — i.e. that the Defendant might be there — was new to them. Accordingly, the Court finds that the search of Defendant’s bedroom was unreasonable under the Fourth Amendment....
Id. at 161-62.
The government filed a timely Notice of Appeal of the District Court’s Order granting the motion to suppress and a certification, pursuant to 18 U.S.C. § 3731, that the appeal “is not taken for purpose of delay, and that the evidence suppressed pursuant to the November 20 Order is a substantial proof of a fact material in the proceeding.”
ANALYSIS
I. Evolution of the Protective Sweep Doctrine
The Fourth Amendment protects “[t]he right of the people to be secure in their person, houses, papers and effects against unreasonable searches and seizures.” U.S. Const, amend. IV. Because “the physical entry of the home is the chief evil against which the wording of the Fourth Amendment is directed,”
Payton v. New York,
Buie had its genesis in the armed robbery of a restaurant by two men, one of whom was wearing a red running suit. Investigation apparently led to Buie and an accomplice, and police secured arrest warrants for both. After conducting surveillance of Buie’s house and learning that he was inside, police officers entered and dispersed throughout the first and second floors. One officer shouted into the basement, identifying himself as the police and asking anyone present to come out. Buie eventually emerged and was taken into custody. Thereafter, another officer entered the basement where Buie had been to search for anyone else who might be there. Although no one else was found to be present, the officer did discover a red running suit in plain sight atop a pile of clothes. It was this suit that Buie sought to suppress at the trial, where he ultimately was convicted by a state court jury for robbery with a deadly weapon and using a handgun in the commission of a robbery.

In articulating the protective sweep doctrine, the Supreme Court found “most instructive” its holding in
Terry v. Ohio,
The Supreme Court in
Buie
formulated the issue before it as “what level of justification is required by the Fourth and Fourteenth Amendments before police officers, while effecting the arrest of a suspect in his home
pursuant to an arrest warrant,
may conduct a warrantless protective sweep of all or part of the premises.”
Id.
at 327,
We have interpreted the
Buie
decision to allow a protective sweep of a house where entry was made by police pursuant to “lawful process.”
See United States v. Miller,
In arriving at our conclusion in Miller, we observed that “[a]t the core of Terry, Long and Buie is the common understanding that the Fourth Amendment’s reasonableness requirement is sufficiently flexible to allow officers who have an objectively credible fear of danger to take basic precautions to protect themselves.” Id. at 98. Accordingly, we proceeded to
hold that a law enforcement officer present in a home under lawful process, such as an order permitting or directing the officer to enter for the purpose of protecting a third party, may conduct a protective sweep when the officer possesses articulable facts which taken together with the rationale inferences from those facts would warrant a reasonably prudent officer in believing that the area to be swept harbors an individual posing a danger to those on the scene.
Id. (internal quotation marks and alteration omitted). We found justification for the officer’s concern for his safety in the order of protection itself, in the officer’s knowledge that an emotional domestic dispute was involved and, of course, in the *86 threat by the subject of the order that he would shoot his former roommate in the head. Id. at 101.
Where officers cannot supply specific and articulable facts warranting a reasonably prudent officer to believe that an individual posing a danger is lurking in an area to be swept, we have found lacking an essential element necessary to justify a search under the protective sweep doctrine as defined in
Buie. See United States v. Vargas,
A similar lack of specific facts as to the presence of a lurking danger foreclosed application of the protective sweep doctrine in
United States v. Gandia,
Rejecting the application of the protective sweep doctrine for lack of an essential element, in Gandía we found that there was “nothing in the record from which a reasonable police officer could have inferred that there was a specific danger of unknown third-parties hiding in [defendant’s] apartment.” Id. at 264. With respect to the question of consent, we provided this caveat: “Although we do not decide this issue, we do note that when police have gained access to a suspect’s home through his or her consent, there is a concern that generously construing Buie will enable and encourage officers to obtain that consent as a pretext for conducting a warrantless search of the home.” Id. at 262. And with further respect to the basis for entry in the application of the protective sweep doctrine, we had this to say in Gandía: “In the instant case— unlike when officers enter a suspect’s home in order to execute an arrest warrant or under exigent circumstances— there was no need for the police officers to enter [defendant’s] home in the first place. They were there for their own convenience (and perhaps for his) while taking his statement.” Id. at 263.
There exists a circuit split amongst our sister circuits relevant to the proper basis for entry into a home in connection with the conduct of a protective sweep. The Ninth and Tenth Circuits have applied the protective sweep doctrine only where entry has been made incident to an arrest in
*87
the home, declining to extend the specific parameters of the doctrine as announced in
Buie. See United States v. Torres-Castro,
The First, Fifth, Seventh, and D.C. Circuits have extended the doctrine to allow protective sweeps of living quarters in non-arrest situations.
See United States v. Martins,
II. The Protective Sweep Doctrine and the Search of Hassock’s Bedroom
Although we have joined the majority of our sister circuits to the extent that they conclude “that specific, articulable facts giving rise to a reasonable inference of danger may justify a protective sweep in circumstances other than during the in-home execution of an arrest warrant,”
Miller,
In
Gould,
the Fifth Circuit found that the officers were “in the mobile home for a legitimate governmental purpose,” and that purpose was to question the defendant about information they had received about the defendant’s threat to kill two judges.
Gould,
Similarly, in
United States v. Patrick,
In this case, it is not necessary to determine whether the protective sweep exception is limited to situations involving the execution of legal process (as was the case in Miller) or extends (as the government urges) to any situation where police are lawfully on the premises for a legitimate governmental reason antecedent to the sweep. Certainly the agents here had no legal process and, although they went to the Hassock apartment with a legitimate purpose — the questioning and possible arrest of Hassock — when Hassock did not answer the door, that purpose could not be pursued until Hassock was found. Under these circumstances, the sweep cannot be viewed as a reasonable security measure incident to Hassock’s interrogation or arrest. Instead, the “sweep” itself became the purpose for the agents’ continued presence on the premises insofar as they thereby searched the location for Hassock. As the district court found, it may have been objectively reasonable for agents to think that Hassock’s presence on the premises posed a danger to their safety.
See United States v. Hassock,
In a post-argument submission, the government asserts that a legitimate investigative purpose for a protective sweep after the initial meeting with the woman was, based on her questionable consent, to look around the “common area” of the apartment to locate Hassock and to determine whether he was “willing to be interviewed.” The government did not advance this theory in the District Court, presenting no evidence that would allow the District Court to assess its credibility, let alone its legal sufficiency. Accordingly, we deem it forfeited on appeal.
See, e.g., Kendall v. Emps. Ret. Plan of Avon Prods.,
CONCLUSION
For the foregoing reasons, we affirm the judgment of the District Court suppressing the firearm found in Hassock’s bedroom.
