U.S. officials say an American citizen on a flight from Paris to Atlanta claimed to have a fake passport and said he had explosives in his luggage.
The officials say federal air marshals are on the flight and that the cockpit is secure. The flight was diverted to Bangor, Maine, due to the incident. Officials believe the man's passport is authentic.
The officials spoke on condition of anonymity because the investigation is ongoing.
Delta spokeswoman Susan Elliott says there are 235 passengers and eight crew aboard the Airbus 330, which landed safely at 3:37 p.m. EDT at Bangor International Airport.
Federal officials met the aircraft at the airport. The TSA says the passenger is being interviewed by law enforcement.
