Pressure cooker found near scene of New York explosion

NEW YORK — A day after a bombing injured 29 people in a Manhattan neighborhood, police are scouring the area for clues about who was responsible for the explosion and why it happened.

“We know it was a very serious incident, but we have a lot more work to do to be able to say what kind of motivation was behind this,” New York Mayor Bill de Blasio told reporters Sunday. “Was it a political motivation? Was it a personal motivation? We do not know that yet.”

Gov. Andrew Cuomo visited Chelsea where the explosion occurred Saturday night.

It’s still unclear whether that suspicious device has any connection to Saturday’s explosion, which shook New York City’s Chelsea neighborhood and sent panicked people scrambling for cover.

A police bomb squad was still investigating the device Sunday afternoon, NYPD Chief of Detectives Robert Boyce said.

“We don’t have everything in. Think of a jigsaw puzzle out in the street right now,” he said. “Do we think they’re related? Yes, we have to move in that direction, but right now we’re not ready to make those calls yet.”

“We do not have any specific evidence of a connection, but that will continue to be considered,” de Blasio said. “We’re not taking any options off the table.”

City officials called on the public to help them track down who’s responsible.

Investigators are also combing through surveillance video for clues, but so far they haven’t found anything pointing to a suspect, a senior law enforcement official said.

Multiple local and federal law enforcement officials described the pressure cooker found at 27th Street.

None of them would say what was inside the cooker, which has since been removed from the scene. A piece of paper with writing on it was found nearby, the officials said.
