CLAYTON, Mo. (KMOX) - Clayton police are asking for help in catching a man who’s been groping women across the street from the St. Louis County Jail.

Officers say it’s happened at least three times in recent weeks, mostly on weekend evenings.

The man commits the act in a public parking lot, then runs away before his victim has time to react.

He’s described as white or Hispanic, in his early 20′s, under five-foot-ten inches tall, with a thin to medium build and black shoulder-length hair.

Those with information on the suspect are asked to call Clayton Police at 314-645-3000.
