The 23-year-old woman was swiping into the turnstiles of the Prospect Park station at Lincoln Road and Ocean Avenue about 5:20 p.m. when Jaquan Whittle, 25, came up and spanked her, NYPD officials said.
Whittle, who can be seen in video the victim took and police released Tuesday, then followed her onto an Manhattan-bound Q train and sat across from her, smirking and clutching a black plastic bag, police said.
The victim exited the train in Herald Square, but the suspect followed her down an escalator in the station where he grabbed her by the arms, police said.
The victim struggled enough that the suspect bit her chest but then fled, police said.
She refused medical attention at the scene, police said.
Investigators managed to identify who Whittle was and contact his family to negotiate his surrender to police Wednesday, NYPD officials said.
Whittle was arrested for attempted rape, assault, forcible touching and harassment, police said.
Police said he has been arrested many times before, but all their records are sealed.
Anyone with information should contact Crime Stoppers at (800) 577-TIPS (8477).
