A 48-year-old man was shot in the chest while riding on a New York City subway car on Sunday in what appeared to be the latest in a series of random attacks in the city's transit system.
The unidentified gunman fled when the train pulled into a station in Manhattan and remained at large on Sunday evening, Kenneth Corey, NYPD chief of department, said at a news briefing.
"Preliminary investigation reveals the suspect was walking back and forth in the same train car and, without provocation, pulled out a gun and fired it at the victim at close range as the train was crossing the Manhattan Bridge," Mr Corey said.
The gunman, described only as a heavy-set, "dark-skinned" man with a beard wearing a hooded sweatshirt and sweat pants, fled when the train pulled into the next station, Mr Corey said.
