Cops are looking for a man who allegedly raped and beat a woman in the Bronx Saturday — leaving the 20-year-old victim so badly injured that one Special Victims Division investigator described the attack as “one of the worst he’s ever seen,” police sources said.

The victim met parolee Temar Bishop, 23, with other friends and ended up hanging out with him on a rooftop on Alexander Avenue in Mott Haven, sources said.

Bishop allegedly punched her in the face numerous times and then raped her, police said.

After the sexual assault, he allegedly punched and kicked her in the head and body until she passed out, police said.

She suffered a fractured nose and lacerations to her face and body and was treated at a hospital.

Bishop was locked up for just over a year on a third-degree robbery charge at Altona Correctional Facility and was release on parole July 9, 2018. He was also arrested twice in 2016 for robbing a 99 Cent store.

Police released photos of Bishop on Monday.
