Police are looking for a man who they say groped a woman on a crowded 4 train in the Bronx last month.

Investigators say the victim snapped a picture of the man before he got off at the 170th Street stop.

This incident happened on July 9 during the evening rush hour.

He's described as being 5'6" tall, weighing 150 pounds with black hair and a clear complexion.

Anyone with information about either case is asked to call Crimestoppers by calling 1-800-577-TIPS, by texting TIP577 to CRIMES, or by going to NYPDCrimeStoppers.com.
