Surveillance video captured a would-be rapist trying to grab and tear the clothes off a woman who was walking her dog in Inwood yesterday morning, police said.

The suspect ran up behind his 30-year-old victim and her tiny dog on West 212th Street near Inwood Hill Park and Isham Park at 6:55 a.m., cops said.

The creep grabbed the woman and tried to rip her clothes off, according to police. The victim can be seen struggling to break free as her dog scurries around her feet. She eventually fought off her attacker, who fled, cops added.

The suspect is believed to be in his late 20s, about 5-foot-11 and 180 pounds. He was wearing a white T-shirt, blue denim shorts and a brown or red baseball cap.
