Cell phone cameras: bane of the modern groper, flasher and fondler! Just ask this guy, who is wanted by the police for allegedly making obscene gestures at and then forcibly groping a woman in Brooklyn on Wednesday.

The incident started around 1:30 p.m. when a 24-year-old woman got on the S train at Franklin Avenue. The man in the photo sat across from her and, she says, began making obscene gestures. She snapped a photo and then got off the train—but so did he.

According to the police, as the woman climbed the stairs to leave the station the man forcibly grabbed her butt from behind. She then turned around and slapped him in the face "causing him to flee in an unknown direction."

Police don't think he is connected to the Brooklyn serial groper but would still love any and all information on the man. If you know anything, call or text Crime Stoppers at 1-800-577-TIPS.
