Man With Explosives Tries To Board Plane

PHILADELPHIA - March 29, 2012 (WPVI) -- A 29-year-old man has been taken into custody at Philadelphia International Airport after allegedly attempting to board a plane to San Francisco while carrying a plastic bottle filled with explosives in his carry-on luggage.

The bottle, which was in the man's backpack, contained explosive (pyrotechnic) powder and three M-80 type fireworks.

Sources say a federal background check showed no initial connection to terrorism and that the man told authorities he had "fooled around" with the materials and forgot he had it in his backpack as he attempted to board the flight.

The Philadelphia Police Bomb Squad removed the material to their range for examination.
