Police are hoping the public can help them find a man accused of groping a woman, and then attacking her after she tried to defend herself.

The incident occurred on September 16th, around 10 p.m. According to the NYPD, a 45-year-old woman had left a northbound 7 train at the 103rd Street and Roosevelt Avenue subway station and was walking down the stairs "when the individual touched her buttocks."

The victim then turned and hit the suspect in the chest, police say, but then the suspect punched her in the face and fled the station eastbound on Roosevelt Avenue. The victim refused medical attention at the scene.

The NYPD released images of the suspect, describing him as about 30 years old, 5'6" and 140 with black hair and brown eyes. Police say he was last seen wearing a white shirt and gray shorts, but the images distributed by the NYPD show him shirtless.

Anyone with information in regards to this incident is asked to call the NYPD's Crime Stoppers Hotline at 800-577-TIPS or for Spanish 1-888-57-PISTA (74782). The public can also submit their tips by logging onto the Crime Stoppers Website at WWW.NYPDCRIMESTOPPERS.COM or texting their tips to 274637(CRIMES) then enter TIP577. All calls are strictly confidential.

If you see or experience sexual misconduct in the subway (this includes seeing a masturbator, being groped, being grinded on, etc.), you can report it to the MTA and police on this website. There's also a place for you to upload photos and/or video. Don't let the perverts win.
