PREGERSON, Circuit Judge:

Petitioner Benitez-Mendez seeks review of a decision of an immigration judge, affirmed by the Board of Immigration Appeals, finding petitioner deportable under 8 U.S.C. § 1251(a)(2) for entry without inspection. This court has jurisdiction under 8 U.S.C. § 1105a(a).

Petitioner was arrested by Border Patrol officers on April 13, 1981, while he was standing in a hop field near Granger, Washington. He had been working the field with a' group of workers who fled when three marked Border Patrol vehicles approached the field. Petitioner did not run but remained standing in the field. A Bor *1108 der Patrol officer approached and questioned petitioner, who told the officer that he had papers in his car which showed his legal alien status. Petitioner was then detained in a Border Patrol vehicle while the officers examined his papers.

After the officers determined that the papers did not establish that petitioner was legally in the country, petitioner was arrested and taken to the Border Patrol office. At the office, he told the arresting officer that he was born in Mexico and that he had entered the United States near San Ysidro without an immigration inspection. The arresting officer wrote this information on a Form 1-213 (Record of Deportable Alien). At his deportation hearing on May 21,1981, petitioner denied the allegations in the Order to Show Cause, denied deportability, and unsuccessfully moved to suppress the information contained on the Form 1-213.

Petitioner contends that he was unlawfully seized within the meaning of the Fourth Amendment, and that, therefore, the information obtained by the Border Patrol and used at the deportation hearing should have been excluded as the “fruit of an unlawful seizure.”

This court’s test to determine whether the factual circumstances of law enforcement activity rise to the level of a seizure under the Fourth Amendment is found in United States v. Anderson, 663 F.2d 934 (9th Cir.1981):

“[A] person has been ‘seized’ within the meaning of the Fourth Amendment only if, in view of all of the circumstances surrounding the incident, a reasonable person would have believed that he was not free to leave. Examples of circumstances that might indicate a seizure, even where the person did not attempt to leave, would be the threatening presence of several officers, the display of a weapon by an officer, some physical touching of the person of the citizen, or the use of language or tone of voice indicating that compliance with the officer’s request might be compelled.”

Id. at 939 (quoting United States v. Mendenhall, 446 U.S. 544, 554, 100 S.Ct. 1870, 1877, 64 L.Ed.2d 497 (1980) (opinion of Stewart, J.)); see ILGWU v. Sureck, 681 F.2d 624, 631 (9th Cir.1982), cert. granted sub nom. INS v. Delgado, - U.S. -, 103 S.Ct. 1872, 76 L.Ed.2d 805 (1983). When the stop in question rises to the level of a “seizure” under the Fourth Amendment, we have formulated a constitutional standard applicable to detentive questioning of suspected illegal alien workers. In ILGWU v. Sureck, we held that

INS investigators may not seize or detain workers for citizenship status questioning unless the investigators are able to articulate objective facts providing investigators with a reasonable suspicion that each questioned person, so detained, is an alien illegally in this country.

681 F.2d at 638. These two standards are applicable to the seizure of petitioner Benitez-Mendez.

From the record, it does not appear that the Border Patrol officer’s initial encounter with petitioner amounted to a seizure under the Anderson test. The officer approached petitioner in an open field and asked him several questions to which he responded voluntarily. There is no evidence of the use of physical force, a display of a weapon, or the threatening presence of several officers.

However, following the initial questioning during which petitioner stated that he had immigration documents in his car, the Border Patrol officer took petitioner to the Border Patrol vehicle and put him inside to wait until other officers could check his papers. We find that the placing of petitioner in the Border Patrol vehicle was a seizure under the Anderson test. Border Patrol Agent Minyard testified that he directed a second Border Patrol officer, Agent Stinsley, to keep petitioner in the Border Patrol vehicle until his papers could be examined. Once petitioner was placed inside the vehicle and told to wait, it is clear that he reasonably “would have believed that he was not free to leave.” Anderson, 663 F.2d at 939.

*1109 Having determined that the detention of petitioner in the vehicle was a seizure, we find that the Border Patrol officer was not able to articulate objective facts providing a reasonable suspicion that Benitez-Mendez was an alien illegally in this country. ILGWU v. Sureck, 681 F.2d at 638. The objective facts known to the officers at the time of petitioner’s detention were that petitioner was a field worker whose co-workers had fled upon sight of a marked Border Patrol detail, that he was an alien, and that he claimed to possess documents showing his legal status. Agent Minyard, who ordered petitioner detained in the vehicle, did so over the radio solely upon the information conveyed by Agent Stinsley that “he had a person there who claimed to be legal status; however, his papers was (sic) in his vehicle.”

In sum, the Fourth Amendment standard articulated in ILGWU v. Sureck has not been met in this case. At the time that Agent Minyard ordered Agent Stinsley to seize and detain petitioner, neither officer had sufficient grounds to suspect that petitioner was an alien illegally in this country.

Because petitioner’s arrest violated the Fourth Amendment, petitioner contends that the information obtained as a result of that arrest was inadmissible at his deportation hearing. Recently, this court applied the exclusionary rule to deportation hearings, holding that the INS is barred from using in those hearings statements made as products of an unlawful detention. Lopez-Mendoza v. INS, 705 F.2d 1059, 1075 (9th Cir.1983) (en banc). In light of this decision, we conclude that petitioner’s statements on Form 1-213 were inadmissible at his deportation hearing and reverse the order of deportation.

REVERSED.
