Today we once again hold that an individual is not arrested but merely detained when, at the border, he is asked to exit his vehicle, briefly handcuffed while escorted to the security office, uncuffed, patted down, and required to wait while his vehicle is searched.
*943 I. Facts
On December 1, 2002, at around 8:50 p.m., defendant Enrique Nava drove to the San Ysidro, California port of entry into the United States. Inspectors Santiago and Sloat were patrolling cars in “prepri-mary” — an area where cars'are lined up to approach a primary inspection booth— when their narcotics detector dog alerted on the gas tank of Nava’s pickup truck. Nava was asked to shut off his engine. He stated he had nothing to declare, and indicated that he was the owner of the vehicle. He was asked where he had been and, where he was going, and he responded. Nava was asked for his identification and vehicle registration, and, as he took his identification out of his wallet, Santiago noticed Nava’s hands were shaking. Santiago also noticed that after Nava had given over his license, “he was tossing his wallet side to side, you know, like, playing with it,” which was “another sign of nervousness” to Santiago. Santiago further stated that he noted Nava’s carotid artery was “pumping” and Nava’s “body was tensing up.”
Santiago then asked Nava to exit the vehicle, handcuffed him, and then escorted him to the security office. Santiago later testified that “I pretty much just said for safety reasons, sir, I am going to have to handcuff you and escort you to the security office.” Santiago stated that “[fit’s always the statement I make.... It’s more like a consideration for the traveling public, ... not to scare them. Let them know you are not being arrested.” He specifically said that he recalled making this statement to Nava.
The security office was located about 400 feet away from Nava’s vehicle, and the walk there took around two or three minutes. At the office, Santiago removed the handcuffs, patted Nava down, and searched his shoes. Nava was also relieved of his wallet and keys.
Inspector Michelle McGinn was working secondary inspection that evening when Nava’s pickup came in around 9:00 p.m. McGinn testified that she first looked under the truck “because [she] was informed that there was an alert to the gas tank.... [A]nd I noticed that there were scratch marks on the gas tank.” This indicated to Inspector McGinn that there had been some tampering with the gas tank. McGinn then tapped the gas tank with her flashlight and “received a solid sound.” She testified that this indicated there was something inside of the gas tank, as an ordinary gas tank that is filled just with gas will produce a “ringing sound.” McGinn testified that she had performed such a tapping procedure over 100 times, and had been taught by other inspectors to perform this procedure. When there is some solid material in the gas tank,”[y]ou get a solid sound. It makes a thump.” McGinn also said that tapping the gas tank is part of the “seven-point inspection” normally done at secondary.
At 9:30 p.m. McGinn called for a mechanic to remove the gas tank. The mechanic arrived .around 10:00 p.m., and, when the vehicle was raised on the .lift, McGinn noticed fresh tool marks on the bolts and a broken bolt, which indicated to her that the truck bed had been recently removed. The gas tank was removed, and, at around 11:00 p.m., 23.20 kilos of marijuana were found inside. At around 3:05 a.m., Nava was placed under arrest, was read his Miranda rights, and confessed that he knew there were drugs in the gas tank.
The district court denied Nava’s motion to suppress his post-arrest confession and the drugs found in his truck. The court explicitly found that “it really wouldn’t have mattered whether the dog alerted or not,” as “there is no requirement for reasonable suspicion to contact a driver in a *944 preprimary position.” 1 He stated, “You can go up to any vehicle at any time for any reason.” The court ruled that the search became non-routine when McGinn requested that the contractor remove the gas tank; “[hjowever, I believe that there was actual probable cause for this non-routine search, based on the information that was known to Agent McGinn.” As to Nava’s arrest, the court ruled that Inspector Santiago’s asking Nava to step out of his truck and handcuffing him and escorting him to the inspection area was a detention, not an arrest. The court reasoned that “it’s reasonable that he would be asked to remain there until the search was completed.... Of course, once they found the marijuana, probable cause attached and he was arrested.”
During the suppression hearing, Nava’s attorney requested that additional discovery material relating to the drug sniffing dog be provided, but the district court stated in response that “[w]e may or may not even get to that, depending on the testimony.” There is no other mention of this discovery request during the suppression motion hearing. The district court expressly did not rely on the dog in reaching the conclusion that the officers’ conduct was reasonable under the circumstances.
II. Jurisdiction and Standard of Review
We have jurisdiction pursuant to 28 U.S.C. § 1291. The determination of probable cause to arrest a suspect is a mixed question of law and fact reviewed de novo.
United States v. Carranza,
III. Discussion
A. The search of the truck was legal, and the drugs found in the gas tank are therefore admissible.
Nava argues on appeal that the search of the gas tank was non-routine and the government has not met its burden justifying it. As a result, Nava argues, the drugs found were the fruits of an illegal
*945
search and should be excluded. Although we had held that border officials must have “reasonable suspicion” to justify the removal of a vehicle’s gas tank,
United States v. Molina-Tarazon,
B. Nava’s detention was legal and his post-arrest statements are therefore admissible.
Nava’s second argument on appeal is that when he was handcuffed and escorted to the secondary area he was “arrested,” and not merely “detained,” because a reasonable person would not have felt free to leave or that his detention was a mere “border crossing formality.” He focuses on the facts that he was not told that if the officers found nothing he would be free to leave, that he was handcuffed and not told it would be temporary, and that his identification and keys were kept from him while he was waiting for hours at secondary. According to Nava, probable cause did not exist to justify this arrest; as a result, his post-arrest confession should be excluded as the fruit of an illegal arrest.
United States v. Bravo,
This case is also similar to a companion case to
Bravo, United States v. Zaragoza,
*946
Nava was asked to exit his vehicle, briefly handcuffed and told that the handcuffs were for safety reasons, told he was being escorted to a secondary waiting area, un-cuffed, had a pat-down search conducted, and was asked to wait while his truck was searched. The only differences between Nava’s detention and the detentions in
Bravo
and
Zaragoza
are that Nava was not explicitly told the handcuffing was temporary (but was told instead that the handcuffing was for safety reasons), he was not told he would be free to leave if nothing was found in his truck, and Nava was required to wait a longer period of time than the defendant in
Bravo.
However, these differences do not warrant a different result. The handcuffs remained on Nava for only a couple of minutes. If a person can be detained in a locked security office while his vehicle is searched, we can perceive no reason why he cannot be handcuffed for the two minutes it takes to get him there. The agents should not have to worry about the person becoming combative or trying to escape while being taken to the security office.
Cf. United States v. Hernandez,
Nava cites numerous cases that stand for the notion that an effective seizure by the police amounts to an arrest requiring probable cause.
See, e.g., Dunaway v. New York,
In sum, we conclude that Nava’s being asked to leave his truck, being handcuffed and told it was for safety reasons, being escorted in handcuffs to the security office, having had a pat down search conducted, and being forced to wait in the locked security office while his truck was searched did not constitute an arrest under the Fourth Amendment. Rather, it was a reasonable border detention. He was not arrested until the marijuana was found. His subsequent incriminating statements were therefore not the fruit of an unlawful arrest. 2 The district court did not err in denying the motion to suppress.
AFFIRMED.
Notes
. While the district court expressly stated it was not relying on the dog search, and while no suspicion of any kind is needed to stop a car entering the United States and ask the kinds of questions Inspector Santiago posed to Nava,
see Molina-Tarazon,
. We also agree with the government’s alternative argument that the discovery of drugs in Nava's gas tank constituted intervening and independent probable cause to arrest him, irrespective of the legality of his detention. As we have explained, the border officials had *947 the right to search the truck and remove the tank. The resulting discovery of the marijuana provided probable cause to arrest Nava. His subsequent interrogation was, therefore, not the fruit of an illegal arrest.
