Federal agents arrested a Pennsylvania man this week after he allegedly tried to bring explosives in his suitcase on a flight from Lehigh Valley International Airport to Florida. Marc Muffley, 40, faces two charges, according to a federal complaint, including possession of an explosive in an airport and possessing or attempting to place an explosive or incendiary device on an aircraft. A federal judge Thursday ruled that Muffley remain in custody pending trial, finding that he posed a danger to the community and was a flight risk. Muffley did not enter a plea during Thursday’s hearing.
