Police arrested a man they said set a woman on fire while she appeared to be asleep on a New York City subway train on Sunday morning, killing her. The woman, who has not been identified, sat motionlessly aboard a stationary F train at the Coney Island-Stillwell Avenue subway station in Brooklyn at about 7:30 a.

Police said an unknown male had approached the woman, set her on fire, and then left the subway car around 7:30 a.m.

The "person of interest" was taken into custody hours after the attack while riding another train, according to NYPD Transit Chief Joseph Gulotta.
