Chief Inspector Joseph Sullivan says 29-year-old Joseph Picklo of Dallas, Pennsylvania is charged with possession of a destructive device for allegedly carrying explosives to a security checkpoint Thursday morning.
Authorities told our sister station, 6abc/Action News in Philadelphia, that Picklo described himself as a self-employed salesman who "likes to conduct experiments with explosives."
Authorities say he was found carrying a plastic bottle filled with explosives in his carry-on luggage.
The bottle, which was allegedly in Picklo's backpack, contained explosive (pyrotechnic) powder and three M-80 type fireworks, investigators told Action News.
A police spokeswoman said earlier the explosives may have been left in a bag accidentally. Sullivan says the situation is still under investigation.
An airport spokeswoman says the checkpoint was closed for about 30 minutes but no flights were delayed.
