LOS ANGELES - A MAN who allegedly claimed to have a bomb aboard a jetliner and lunged for a door after it landed in Los Angeles was tackled by other passengers and held for questioning on Wednesday, authorities said.

Delta Air Lines Flight 110 from Atlanta was only minutes from landing at Los Angeles International Airport shortly before 10.30am when the incident occurred.

The man 'jumped up and started running ... (and) yelled 'I've got a bomb,'' passenger Bruce Worrilow told Fox 11 News.

The plane touched down a minute or two later and as it rolled toward the terminal, the man 'lunged for an exit door and also assaulted a passenger,' prompting passengers and the flight crew to bind him with plastic ties, said FBI spokesman Laura Eimiller.

'He did not have a bomb on his person,' but his bags and the airplane were searched, Ms Eimiller said.

FBI agents and airport police took the man into custody. He was being questioned but had not been arrested by mid afternoon.

The motive for the alleged threat was not immediately clear, Ms Eimiller said.

None of the 271 passengers aboard the aircraft were hurt and no other flights were disrupted, said Delta spokesman Betsy Talton. -- AP
