Five bombs found in package at N.J. train station, one explodes as robot examines it

ELIZABETH, New Jersey -- A backpack containing multiple bombs was found Sunday night near an Elizabeth, New Jersey, train station, according to the FBI and the city's mayor.

The backpack had up to five devices, Elizabeth's mayor Chris Bollwage said. It was found in a wastebasket, outside a neighborhood pub and located about 500 feet from a train trestle. No one was injured.

On Sunday around 9:30 p.m., two men found the backpack and thought it might contain something valuable. They alerted police when they saw wires and a pipe, the mayor said. No cell phones or electronic timing devices were found on the devices, Bollwage said.

There is no indication whether the latest incident in Elizabeth is connected to the bombing in a New York City neighborhood that injured 29 people and the explosion from a garbage can near a charity run in New Jersey. In the other New Jersey incident, investigators discovered three pipe-bomb-type devices wired together, but no one was wounded.

Bomb technicians arrived to the scene in Elizabeth and sent in a robot to examine the devices. During the process, one of the devices detonated.

"The robots that went in to disarm it, cut a wire and it exploded," Bollwage said.

The remaining four devices will be transferred in protective cases to a local site and then will be taken to the FBI laboratory at Quantico, Virginia, Bollwage said.

Police checked all garbage cans in the immediate area, but found no other suspicious items.

Trains resumed Monday morning after the New Jersey Transit had suspended service going through Elizabeth station on Sunday night. Both New Jersey Transit and Amtrak warned of delays following the incident.

Elizabeth is located about 16 miles southwest of New York City.
