New York explosion: 1 in custody after blast at Port Authority bus station

An explosion struck the Port Authority bus terminal at 42nd Street and Eighth Avenue on Monday morning, the New York Police Department said in a tweet. The station is one of the busiest commuter hubs during rush hour. The the A, C and E subway lines are being evacuated, NYPD Sgt. Brendan Ryan said. One male suspect is in custody. No other injuries other than the suspect have been reported at this time, according to the NYPD.  Preliminary information, according to two law enforcement sources, one local and one federal, indicates a pipe bomb may have unintentionally exploded.  Another New York police source says a man in custody may have set off a device, injuring himself. Francisco Ramirez said he heard two explosions as he was exiting a bus about 7:45 a.m. ET. He heard both blasts distinctly even though he was wearing headphones. "From what I saw it sounded like it came from the subway, but I'm just guessing," he said. "It was two distinct explosions seconds from each other. As I was making my way toward the outside, I kept getting shoved by cops and there were cops at every entrance blocking and there was police and SWAT everywhere. "It was scary. It was just a lot of chaos but I didn't see any injuries."
