Cops are looking for a jerk who they say masturbated on the subway in Windsor Terrace earlier this month.
The sicko was on a Coney Island-bound F train at around 7:39 pm on Jan. 6 when he whipped out his junk and pleasured himself in front of a female straphanger, according to a report.
The perv then got off in a different way when he fled the carriage at the Fort Hamilton Parkway stop, police said — but not before someone snapped a photo of him.
Police say the suspect is between 30 and 35 years old, stands 6-feet tall, and weighs 180 to 190 pounds. He was last seen wearing a black jacket, gray sweat pants, white ski cap, and white sneakers, cops said.
