NEW YORK — A gunman in a gas mask and a construction vest set off a device that poured smoke into a crowded northbound N train in Brooklyn before shooting fire early Tuesday, shooting 10 people and injuring six others, police sources said.
The gunman remained at large.
The mayhem began just before 8:30 a.m. on the N/R line going through Sunset Park. The gunman was sitting quietly in the train’s second car before he “donned a gas mask,” NYPD Police Commissioner Keechant Sewell said at a Tuesday afternoon news conference.
