A dog-walker fought off a creep who placed her in a headlock and tried to kiss her in Riverside Park last week, at one point biting him on the lips, cops said.

The 48-year-old victim was walking her dog inside the park at 107th Street and Riverside Drive on Aug. 5 at 5:20 a.m. when the man approached and asked her for the time.

He then proceeded to grab her and place her in a headlock, cops said.

The plucky woman hit her attacker in the groin, prompting him to release her.

He again tried to place her in a headlock and tried to kiss her — before the woman bit him on the lips, according to police.

He then released her a final time and fled, cops said.

The suspect, depicted in a police sketch, is between 20 and 30 years old and 145 to 155 pounds, cops said. He has a medium complexion, a muscular build, brown, short curly hair and brown eyes.

He was last seen wearing a gray shirt, khaki shorts and white sneakers.
