Cops are looking for a creep who allegedly raped and robbed a woman on her Bronx rooftop early Thursday.

The perv followed the 23-year-old victim as she walked into the elevator of her building at Park Avenue and East 161st Street in Concourse Village around 12:45 a.m., cops said.

Once inside, he choked until she passed out, according to police.

When the woman regained consciousness, the attacker shoved her into a stairwell and forced her onto the rooftop of her building, where he raped her, cops said.

He demanded his victim’s wallet — holding between $40 and $50 — before taking off.

The suspect is about 30 years old, around 5-foot-10 and 180 pounds, cops said. He had black hair in a high-fade afro, and a black beard, cops said.

He was last seen wearing a black jacket, a red flannel shirt, dark pants and black sneakers.
