A woman was raped at knifepoint in Central Park on Monday by a man who offered to walk her home and then violently attacked her, cops said.

The 35-year-old woman was near West 110th Street and Lenox Avenue around 9 p.m. when the suspect approached her and escorted her into the park, according to police.

While they were in the park, the man pulled out a knife and physically assaulted, then raped the victim.

The attacker then ran off with the woman’s purse and cellphone.

The suspect is described as about 30 years old and weighing about 130 pounds.

Cops were on the hunt for him Thursday night.
