(Reuters) - Houston police dispatched a bomb squad on Tuesday to George Bush Intercontinental Airport to investigate a possible bomb threat against a Delta Air Lines plane, a police spokesman said, but no device was found on the airplane.
Bill Begley, spokesman for the Houston Airport System, said the plane has since departed the airport.
"It is a non-specific threat," he said. "We worked with the airline and with TSA to pull the passengers and baggage off the plane and re-screen them.”
Officials at Delta (N:DAL) were not immediately available for comment.
The airport and police did not give the flight number or any additional details about the flight.
The plane was preparing to depart earlier on Tuesday when it was called back to the gate for a security check, local TV station KHOU said.
