Police are asking for help in identifying a man accused of groping at least three teenage girls at the 167th Street station in the Bronx.

Police say the incidents all happened within minutes of each other. According to police, the suspect first grabbed a 16-year-old around 3:20 p.m. on Dec. 15, then repeated the offense about 25 minutes later with another 16-year-old.

About an hour later, officials say he touched a 15-year-old girl.

Anyone with information related to this case is asked to contact police.
