A federal grand jury in Philadelphia indicted Joseph Picklo on August 23, charging him with possession of an explosive in an airport and carrying an explosive on to an aircraft. Federal investigators said that on March 29 this year Picklo attempted to pass through security screening with explosives in his backpack at Philadelphia International Airport (PHL). Airport security officials searched the backpack and confiscated two M80-style fireworks, flash-powder in a concealed container, a lighting wick and a flammable lighter.
