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.

New York City police announced Sunday they have in custody a “person of interest” in the early morning death of a woman who they believe may have fallen asleep on a stationary subway train before being intentionally lit on fire by a man she didn't know.

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