Chief Inspector Joe Sullivan says a man removed from US Airways Flight 1267 at Philadelphia International Airport is not a suspect and did nothing wrong.
Sullivan says police are treating the hoax seriously. He says "this is no joke, this is no laughing matter."
Sullivan says someone called police at the Philadelphia airport and named a passenger who was in possession of a dangerous substance. That prompted a flight en route to Dallas-Fort Worth International Airport to be recalled. The plane was searched by bomb technicians and cleared.
Sullivan says someone played "a pretty nasty trick" on the passenger.
