New York - Authorities at Detroit Metropolitan Airport lifted on Thursday a lockdown that had brought traffic to a halt for nearly three hours after the passenger who triggered the security scare was taken into police custody, airport officials said.
The passenger passed through the security checkpoint at the airport's McNamara Terminal around 8.45pm and then walked out of an exit.
He then returned though the same exit without getting screened again, said airport spokesman Brian Lassaline.
Authorities located the passenger in the terminal, which is more than a mile long and has 121 gates, and reviewed video of the incident before issuing the all-clear, Lassaline said.
The passenger was taken into police custody for further questioning, he added.
The terminal is served by Delta Airlines and its partners Air France and KLM, according to the airport website. - Reuters
