Police arrested a man who allegedly set fire to a sleeping homeless woman in a Brooklyn subway car Sunday morning and then calmly watched as she burned, NYPD officials said.

A frightening video obtained by the Daily News shows the woman standing near the door of a stopped subway car at the Coney Island-Stillwell Ave. station. stands, her clothes on fire, while a man sits a few feet away and casually sits on a bench on the platform.

“Officers patrolling an upper level of this station smelled and saw smoke and went to investigate. “What they saw was a person completely engulfed in flames in the carriage,” Police Commissioner Jessica Tisch said of the macabre crime. “With the help of an MTA employee and a fire extinguisher, the flames were extinguished. Unfortunately, it was too late and the victim was pronounced dead at the scene.

“Unbeknownst to the officers who responded, the suspect had remained at the scene and was sitting on a bench on the platform directly in front of the train car,” Tisch added.

Police cameras captured crystal clear images of the man, which were then distributed to the public. Three teenagers recognized the man in the photos and called 911, allowing NYPD and public transit officers to work together to arrest him, Tisch said.

The horrific scene was captured on disturbing video obtained by The News. “This is a person here! Oh shit!” A voice can be heard on the cell phone video as the woman is seen in flames as what appears to be a police officer walks by and speaks into a radio.

The woman’s identity was not immediately released, but sources told The News that she appeared to be homeless and found herself on a stationary F train at the Coney Island-Stillwell Ave. subway station around 7:30 a.m. was sleeping when the suspect set her on fire.

“A person of interest is in custody. “That’s why we’re now calling on the rest of the justice system to step up and do their job,” Transit Director Joseph Gulotta said at Sunday’s press conference. “There must be strong, swift consequences for this person who committed this brutal, brutal murder, and I use that term lightly. There is no place in civilized society for people like him to walk around.”

The victim and suspect did not appear to know each other and had no previous contact before the suspect set the woman on fire, Gulotta said.

The suspect’s identity was not immediately released, but Gulotta noted that the man immigrated to the United States from Guatemala in 2018.

“It’s bad. It’s wrong. Nobody deserves to be burned, regardless of whether they are homeless,” said Kenny Cruz, sitting in a wheelchair outside a convenience store outside the Coney Island/Stilwell Avenue subway station on Sunday. “My heart goes out to this lady.”
