Bachir Atallah told CNN he and his wife, Jessica, were driving back into the U.S. Sunday evening after visiting family in Canada for the weekend when U.S. Customs and Border Patrol agents stopped them for a secondary inspection at the Highgate Springs checkpoint in Vermont.

Atallah, who is originally from Lebanon, said he was told to park his Range Rover and hand over his keys. When he asked the officer why, the officer placed his hand on his gun and told him to exit his vehicle, Atallah said. He said he was then handcuffed and led into a cell, where his belongings were confiscated. He said his wife was put into a cell across from his.

While detained, Atallah said he gave CBP agents the passcode to his phone after they asked for it. Despite his pleadings, agents never told him why he and his wife were being detained, he said. He said he was never read his rights.

Atallah said after he was first handcuffed, he told officers to call his lawyer, his sister Celine Atallah, who works as an immigration attorney.
