Police are looking for the man with a "Team USA" face tattoo who they say masturbated for more than 30 minutes aboard a subway car on Sunday afternoon.
Authorities say that the man was on a Manhattan-bound No. 2 train at the President Street station in Brooklyn when he stuck his hands down his pants and began fondling himself while staring at a 29-year-old woman, the NYPD says.
The man continued to touch himself for about 30 minutes, and another straphanger snapped a photo of the alleged deviant, authorities said.
In addition to his distinctive "Team USA" tattoo on his forehead, it appears that he has another tattoo on his cheek.
Anyone with information about the man is asked to call Crime Stoppers at 1-800-577-TIPS.
