Traffic in a terminal at Detroit Metro Airport is at a standstill after a reported security breach Thursday night, officials said.
Authorities said around 8:45 p.m. a passenger on the secured side of the airport went through an exit lane and turned back into the secured area without going through security.
"Airport officials have the passenger in custody and are questioning them," spokesman Brian Lassaline said in a statement.
Officials said they are not reopening the screening area until their investigation is complete. It was not immediately clear how long that will take.
