Police have defended their response, beginning when officers patrolling the station smelled and saw smoke coming from the F train.

The woman was sleeping on a train car in Brooklyn on Sunday morning when a man approached her, lit her aflame and ran, police said.

Police officials said a man considered a person of interest in Sunday’s deadly train fire was in custody hours after allegedly starting the blaze that killed a sleeping woman. The woman was discovered around 7:30 a.

A manhunt is underway for a man who is believed to have set a woman sleeping in a subway car on fire, leading to her death.
