What we know about second device, pressure cooker, found near Chelsea explosion

CHELSEA, Manhattan — Just blocks away from where an explosion rocked the bustling Chelsea neighborhood Saturday night, a second device in a plastic bag was found and removed from the scene.

An explosion at West 23rd Street and Sixth Avenue Saturday night injured 29 people, one critically. Investigators believe the an explosive device was placed in or near a dumpster.

Moments later, a suspicious device was found in a plastic bag on West 27th Street, just four blocks from where the initial explosion happened.

The object was a pressure cooker with dark colored wiring protruding, connected by silver duct tape to what appears to be a cellphone, officials said. A piece of paper with writing on it was also found nearby.

None of the officials would say at this point what was inside the pressure cooker. It was removed from the scene early Sunday morning by bomb squad. Police say it was to be taken to the department's firing range in the Bronx.

The next stop for the device is expected to be the FBI lab in Quantico, Va., where it will be examined. Among the questions investigators have is whether the device is connected to the pipe bomb that was deployed earlier Saturday in Seaside Park, N.J.

Pressure cookers were used as explosive devices in the Boston Marathon bombing that killed three people and injured more than 260 in 2013.

Police officers and federal agents scoured Manhattan streets with flashlights, robots and dogs early Sunday to ensure there were no other devices in the area. Attention focused on another object in the area, but it turned out to be trash.

Governor Andrew Cuomo said in a news conference Sunday that there was "significant damage" done from the Chelsea explosion, but, "When you see the amount of damage, we really were lucky that there were no fatalities," he said.

Cuomo said there is no reason to believe there are additional threats to Manhattan, but that the law-enforcement presence will be significantly stepped up as a precaution.

He said there is no known link to international terrorism, but that the act was terrorism in the sense that it was designed to instill fear in people. He urged New Yorkers not to let this attempt dissuade them from living their lives as they normally would.

It's still unclear who was behind the explosion, but officials are urging anyone with information to come forward.
