Investigators are examining a suspicious device found in a trash can near a New Jersey train station, and service on the busy Northeast Corridor line has been suspended.

Elizabeth Mayor Christian Bollwage says two men called police and reported seeing wires and a pipe coming out of the package after finding it at about 9:30 p.m. Sunday.

Bollwage says the Union County bomb squad's robotic device indicated the package the men left under a train trestle could be a live bomb. He says the FBI and state police will decide how to remove the device.

New Jersey Transit says service has been suspended between Newark Liberty Airport and Elizabeth. New York's emergency management department says that New Jersey-bound Amtrak trains are being held at New York Penn Station.

A message left with the FBI wasn't immediately returned.

The discovery of the suspicious package comes a day after an explosion in Manhattan injured 29 people, and an unexploded pressure-cooker device was found four blocks away.
