Police in Brooklyn have arrested a person of interest in the depraved killing of a woman who was set on fire aboard an F Trainand burned them on Sunday morning.

Transit officers took the suspect into custody Sunday afternoon after New Yorkers recognized him from NYPD surveillance photos released to the media. According to law enforcement, the suspect, whose name has not yet been released, is a 33-year-old migrant living in a shelter.

The horrific incident occurred aboard a stationary F train in Stillwell, Coney Island avenue Subway station on December 22nd around 7:30 am.

Initial reports said the victim was sleeping on the train when the deranged man set her on fire. NYPD Commissioner Jessica Tisch said during a press conference that the suspect used a lighter to light the victim’s clothing on fire, which immediately set it ablaze.

Sources in a New York Post article said the victim was found with alcohol bottles scattered around, although not immediately clear if the perpetrator used them in the horrific attack.

Officials of the 60th District and Transit District 34, who were patrolling the platform above, rushed to the scene after smelling smoke. They discovered the woman was fully engulfed in flames and immediately extinguished the fire, Tisch said.

Despite officers’ efforts, emergency services pronounced the woman dead at the scene.

Meanwhile, unbeknownst to the officers, the perpetrator sat on a bench in front of the train and looked in at the victim as flames consumed her body.

Tisch explained that three quick-thinking high school students recognized the perpetrator from the surveillance photos and called 911.

“Other public transit officers responded to the 911 call and discovered the man, wearing the same gray hoodie, wool hat, paint-splattered pants and brown boots, also already on another moving train,” Tisch explained. “The police radioed to request that the trains be stopped.”

Transit District 2 officers walked through each car of the stopped train until they located and arrested the suspect without further incident, Tisch said.

“I want to thank the young people who called 911 to help. They saw something, they said something and they did something,” said the commissioner. “This is an example of great technology and even greater old-fashioned policing with great public support.”

Police described the suspect as 5 years old Foot15 cm tall, about 25 to 30 years old and weighs about 150 pounds. He was last seen wearing a gray hoodie, blue jeans, a dark knit hat with a red band and brown boots.

F train service was suspended in both directions between Coney Island-Stillwell Avenue and either Church Avenue or Kings Highway until early afternoon. From 3:45 p.m. the F trains resumed their regular operations with considerable delays.

Police have not yet identified the victim. The investigation is still ongoing.
