At least 10 people shot  on a Brooklyn subway train

NEW YORK — Police are searching for a gunman after at least 10 people were shot on a Brooklyn subway train, causing panic early Tuesday.

The shooting occurred before 8:30 a.m. on a Manhattan-bound N train in Brookyn's Sunset Park neighborhood, Police Commissioner Keechant Sewell said at a news conference.

The train was waiting to enter the 36th Street station when a man put on a gas mask and opened a canister before the train began filling up with smoke and the man began firing, Sewell said

The shooter, whom Sewell described as a Black male with a heavy build, was wearing a green construction vest and a gray sweatshirt, she said.

New York City Fire Department First Deputy Commissioner Laura Kavanagh said a total of 16 people were injured, including 10 people shot.

Five people were in stable but critical condition. Sewell also said none of the injuries were life threatening.

Firefighters responded to a call for smoke at the subway station at 36th Street and 4th Avenue
