New York shooting not being investigated as act of terrorism: NYPD

Sewell assured New Yorkers on Monday that there were no known explosive devices on subway trains, and the event is not being investigated as an act of terrorism "at this time." Sewell later added that she is "not ruling out anything.

"Although this was a violent incident, reportedly we have no one with life-threatening injuries as a result of this case," she said, adding that the investigation was only hours old, and subject to change. At least 16 people were injured in the shooting, 5 of whom are in critical condition.

The suspect was wearing green construction vest and grey sweatshirt, and is described as being a 5'5 black male with a "heavy build."

Police called this a "coordinated attack," according to ABC, meaning that the shooter could have had accomplices, but said it was a "lone gunman" who used smoke devises. Police are actively investigating two subway stations, both the 36th Street and 25th Street stations, both on the same lines, the N, R and D trains.

Governor Kathy Hochul also addressed the public scene, calling the suspect a "cold hearted" and "depraved of heart" individual, saying that the suspect had no care "about the individuals that they assaulted as they simply went about their daily lives."

"This individual is still on the loose. This person is dangerous. We're asking individuals to be very vigilant and alert," Hochul said, adding that this is an active shooter situation.

"I wanted to let him know that the people in the entire state of New York stand with the people of this city, this community, and we say no more," Hochul said, referring to a call with Adams. "No more mass shootings. No more disrupting lives. No more creating heartbreak for people just trying to live their lives as normal, New Yorkers. It has to end it ends now."

"We are sick and tired of reading headlines about crime, whether they're mass shootings, or the loss of a teenage girl, or a 13 year old. It has to stop. I'm committing the full resources of our state to fight this surge of crime, this insanity that is seizing our city, because we want to get back to normal," she said.

White House Press Secretary Jen Psaki told reporters on Air Force One that the city would receive support in any form that they need, saying that senior staff is in touch with Mayor Eric Adams.
