Los Angeles airport officials say a false report of gunshots that sent panicked travelers fleeing came right after officers with guns drawn detained a man dressed in black and possibly carrying a sword.
The sword was plastic, but, soon after, hundreds of passengers raced onto streets or the tarmac, causing major flight delays that the airport was still recovering from Monday morning.
Video shows at least six officers confronting the man, who is dressed as fictional crime fighter Zorro, outside Terminal 7 around 8:40 p.m. on Sunday.
Airport police say false reports of an active shooter quickly spread, and passengers in five terminals evacuated or pushed through security checkpoints.
Airport spokeswoman Nancy Castles said Monday about 280 flights were delayed and at least 27 flights were diverted to other airports.
