Flight cleared after bomb threat at Philly airport

Nothing suspicious has been found after a bomb threat forced security to sweep a flight at Philadelphia International Airport.

Philadelphia authorities say airport police received a call around 8:40 a.m. today from Air Wisconsin, which was operating the US Airways Express flight.

Police spokeswoman Jillian Russell says a man had called the airline and said there was a bomb on the plane.

The flight had just arrived from Norfolk, Va., and had no passengers on board.

Russell says the man who made the threat is in custody in Virginia.

A US Airways spokesman says the threat has not disrupted service.
