A man wearing a construction vest set off a smoke device and opened fire on riders inside a Brooklyn subway car on Tuesday morning, injuring 23 people, according to the authorities.
As the Manhattan-bound N express train pulled into the 36th Street station in Sunset Park at 8:24 a.m., the on-board gunman put on a gas mask, pulled a canister out of his bag that filled the train with smoke, and fired at commuters in the subway car and on the platform, Police Commissioner Keechant Sewell told reporters during a press conference at the scene Tuesday afternoon, April 12.
