Written terror threats were found on board a Thai Airliner scheduled to land at Los Angeles International Airport (LAX) on Tuesday, authorities said.

Written threats saying there was a bomb on board were found in a lavatory of Thai Airways Flight 794, said FBI spokeswoman Laura Eimiller.

The flight from Bangkok landed at LAX at 8:45 p.m. (0345 GMT Wednesday) and was taken to a remote part of the airport, said Eimiller.

About 200 passengers and crew were taken off the plane and a bomb squad was inspecting it, she said, adding that the occupants were being interviewed.

Law enforcement and airport officials were notified at 7:15 p.m. (0215 GMT Wednesday) of an alleged threat on board the aircraft, which was scheduled to land at 8:44 p.m. (0344 GMT Wednesday), said Sgt. Belinda Nettles of LAX Police Department.

Eighteen fire trucks and fire engines were placed on standby at the airport where the aircraft was expected to land, said Devin Gales of the Los Angeles Fire Department.

An investigation was underway to ascertain the person or group responsible for making the threat, Nettles said.

No explosive device had been found so far.
