At least five devices were found in a backpack inside a waste basket in Elizabeth, New Jersey Sunday, Elizabeth Mayor Chris Bollwage told CNN. Cell phones and electronic timers were discovered on or around the items, Bollowage indicated.

The devices were found near a train trestle by two men who found the package in the waste basket and contacted police when they noticed wires and a pipe, the mayor said. As a result, of the discovery, train service has been suspended. One of the devices was accidentally detonated by a law enforcement drone robot meant to disarm it.

Local law enforcement sent in bomb technicians, a HAZMAT team and a drone to examine the suspicious item.

“There is no threat to public safety as the package is being secured and investigated,” Bollwage said.

The discovery comes after two separate bombings happened in New York and Seaside Park, New Jersey Saturday, where 29 people were injured in the explosion in New York’s Chelsea neighborhood. According to reports both blasts appear to be linked.

A third undetonated device was found just blocks away from the explosion in Chelsea. The FBI took five individuals into custody but no charges have been filed.
