Authorities at Los Angeles International Airport are searching a JetBlue aircraft following reports of an unauthorized person trying to get on board.

Airport spokeswoman Nancy Castles says LAX police received a call around 6 a.m. Thursday about somebody possibly on the passenger boarding bridge. No customers were on board.

As a precautionary measure, Castles says, the aircraft was towed from Terminal 3 to a remote area of the airfield. Police are searching the plane.

The aircraft was being prepared for a flight to New York at 6:30 a.m.

JetBlue says Flight 24 was delayed and all passengers and luggage would go through security screening for a second time.
