The police are looking for a man accused of groping a woman in a busy subway station, and have also released footage of the woman chasing the suspect and smacking him on the head.

The incident occurred around 2 p.m. on August 31st, inside the Grand Central-42nd Street subway station. According to the NYPD, "the individual grabbed the 26-year-old female victim's buttocks as she walked down a staircase."

As you can see from the video below, she was not having it—police say she "confronted the individual and chased him through the station but she lost sight of him when he fled the station on foot westbound on 42 Street."

The suspect is described a male approximately 20 to 30 years old, 5'6" to 5'8" and about 225 pounds with eyeglasses. He was last seen wearing a green shirt, black shorts and black sneakers.
