New York, NY —

A bomb scare emptied Pennsylvania Station and disrupted service on Amtrak, commuter trains and city subways for about an hour on Sunday.

The busy commuter hub was evacuated after Raul Claudio, a 43-year-old with past drug offenses, threw a backpack at a ticket counter and said it was a bomb. The threat was a false alarm, and service on all lines was restored at about 1:25pm. Claudio was arrested and faces up to fourteen years in prison.

Also Sunday, a double-decker Gray Line tourist bus was evacuated in midtown Manhattan after a bus company supervisor told police that five male passengers with "stuffed" pockets had raised her suspicions. Police handcuffed five men and searched about 60 passengers before determining there was no threat.

The incidents came days after a second bombing attack in London last week, which prompted New York police to start random inspections of subway riders' bags.
