The Second Device Found In Chelsea Was Made With A Pressure Cooker

On the evening of Sept. 17, a sudden explosion injured at least 29 people on a sidewalk in the Chelsea neighborhood of Manhattan. Authorities believe the blast was caused by a homemade bomb, a theory made stronger by the discovery of a second device on a nearby block a few hours later.

The second device was found on West 27th Street between the Avenue of the Americas and Seventh Avenue, just a few blocks from where the first explosion occurred on West 23rd.

According to the New York Times, officials described the second device as a pressure cooker, similar to the one used in the Boston Marathon bombings in 2013 — however, authorities still don't know what was inside. This was revealed by a police official who spoke to the paper under the condition of anonymity, as the investigation is still underway.

"A photograph of the device that was shared on social media showed a silver piece of cookware with wires and a cellphone attached," the New York Times reported. "The police confirmed the photo was authentic."

Other outlets offered further details on the mysterious device. "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 found nearby," CNN reported.

According to the New York Times, the second device was removed from the scene around 2:25 a.m. by the NYPD bomb squad. It will be taken to the department's firing range, located at Rodman's Neck in the Bronx, where it will be thoroughly inspected by robots.

New York City Mayor Bill de Blasio stated at a news conference late Saturday night that the first explosion and the second device were "an intentional act," but added that there was “no specific and credible threat against New York City at this point in time from any terror organization.”
