A violent creep has attacked three women in Prospect Park since February, sexually assaulting one of his victims on a Monday afternoon, police said.

The suspect first struck on Feb. 24 at about 5:15 p.m., when he ran up behind a 58-year-old woman and yanked on her hair with both hands, police said.

The woman, who was walking between East Drive and Center Drive, was about to fight him off, cops said, and he ran off into the park.

On March 11 at about 4:30 p.m., the suspect attacked a 24-year-old woman in the same area of the park and forced her to perform oral sex on him, police said.

Two days later at about 2:30 p.m., he ran up to a 26-year-old woman and knocked her cellphone out of her hands, cops said.

He then grabbed her by the hair, but she was able to fight him off. Cops say he grabbed her cellphone before running off in the direction of the Prospect Park Zoo.

The suspect is believed to be in his late 20s and about 5-foot-8, police said.
