“The FBI has arrested a man who allegedly attempted to bring an explosive device onto an airplane in Pennsylvania, US authorities said Wednesday. The bomb was discovered by Transportation Security Administration (TSA) personnel on Monday, after the man's checked bag set off an alarm at Lehigh Valley International Airport in the city of Allentown, the federal agency said in a statement. A section of the airport, located about 100 miles (160 kilometers) west of New York, was evacuated as a precaution, the TSA said. ‘FBI and local law enforcement bomb technicians determined that the item was indeed a live explosive device,’ TSA spokeswoman Lisa Farbstein said on Twitter.”
