LOS ANGELES, Ca. - A security breach that delayed about 15 morning flights at Los Angeles International Airport has been resolved after authorities found a man who didn't undergo proper security screening.

United, Continental and other flights were delayed for about two hours. Transportation Security Administration spokeswoman Suzanne Trevino says the breach occurred around 5:00 a.m. Thursday when a man whose carryon was selected for secondary screening took the bag before it could be physically checked.

Security screening at three terminals was halted until the man was located on a United plane and returned to the terminal. His bag was checked, nothing dangerous was found and the incident ended at 6:48 a.m. Thursday.
