Cops are on the lookout for a man accused of rubbing up against a female F train passenger and exposing himself.

The NYPD’s 84th precinct reports that the suspect targeted the woman on a south-bound F last Thursday as it pulled into the Bergen Street station in Carroll Gardens.

The woman said the brazen  perv grinded against her buttocks and then, standing right in front of her, exposed his genitals.

The suspect is described as a male Hispanic, approximately 30-years-old, 5'7" in height, 170 lbs, black hair with a light complexion. He was last seen wearing a gray sweater, black collar shirt and wearing black Beats headphones.

The photos released by the cops were snapped by the woman.
