The NYPD is looking for a man they say exposed himself to a female G train rider last night.

According to investigators, the unidentified 40-year-old victim was riding a southbound G train at around 10:30 p.m. when the suspect, who cops believe to be in his 50s, committed the act of public lewdness.

The victim was able to get a photograph of him, though he fled shortly thereafter.

Anyone with information in regards to this incident is asked to call Crime stoppers at 1-800-577-TIPS (8477). The public can also submit their tips by logging onto the Crime stoppers website or by texting their tips to 274637 (CRIMES) then enter TIP577.
