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 Thursday.
A Transportation Security Administration spokeswoman Suzanne Trevino says the breach happened around 5 a.m. (1100 GMT) when a man whose carry-on was scanned and selected for a physical search walked off with it.
Trevino says the passenger apparently didn't understand that his bag needed more screening but it's unclear how he got through security without being stopped.
The man was found aboard a United plane and returned for another screening. Trevino says nothing dangerous was found and the all-clear was given at 6:48 a.m.
