A massive manhunt was underway on Tuesday in New York for a man who shot 10 people on a packed subway train, donning a gas mask before setting off two smoke bombs and opening fire on terrified commuters.
Police said the incident in Brooklyn was not being investigated as an act of terrorism, with no indication of a motive at this stage. None of the injuries were considered life-threatening.
New York Police Department commissioner Keechant Sewell told a press conference the suspected gunman put on a gas mask just as the train was arriving at the station.
The gunman "opened two canisters that dispensed smoke throughout the subway car," Sewell said. "He then shot multiple passengers as the train pulled into the 36th Street station."
In addition to the 10 gunshot victims, 13 others were injured as they tried to get out of the station or suffered smoke inhalation, according to officials.
"We are truly fortunate this was not significantly worse than it is," Sewell said.
NYPD chief James Essig said the gunman had fired 33 shots. Police later recovered a Glock 17 9-millimeter handgun, three additional ammunition magazines and a hatchet from the scene.
Sewell said they had identified a "person of interest" and described him as a "dark-skinned male" wearing a neon orange vest and a gray hooded sweatshirt.
They did not have anyone in custody, she added.
Police were alerted to the shooting just before 8:30am (12:30pm GMT).
Verified video footage posted on social media showed the train pulling into the 36th Street station, and smoke billowing out the doors as passengers rushed off, some apparently injured.
One of them, Yav Montano, recounted on CNN being inside the car when it began filling with smoke – and shots rang out.
"In the moment, I did not think that it was a shooting because it sounded like fireworks," he said. "It just sounded like a bunch of scattered popping."
There were 40 to 50 passengers inside at the time and they began crowding toward the front, Montano said – but the door to the next car was locked.
"There were people in that other car that saw what was happening. And they tried to open the door, but they couldn't," he said.
