The 32-year-old woman was exiting the F train station at 169th Street and Hillside Avenue at around 10 a.m. when the unidentified man approached her from behind and grabbed her right buttock, before running off in an unknown direction, police said.
The NYPD released several surveillance photos of the suspect as he came through one of the station’s turnstiles and paused to chat on his cellphone. Police described him as a bald man between 20 and 30 years of age with a slim build. He was last seen wearing a white undershirt under a black hooded sweatshirt, black sweatpants and blue Nike sneakers, and he was carrying a black bag.
Anyone with information is asked to call the NYPD’s Crime Stoppers Hotline at 800-577-TIPS.
