@Reminiscence- I also had an experience with a co-worker who couldn't keep his hands off female co-workers, or sometimes even customers. He'd act like he "accidentally" brushed up against their chests or backsides while walking past them in the halls, but it was deliberate. I thought it was just a matter of time before he got called on it.
One female customer finally complained to the manager after she was sexually groped by that co-worker as she was leaving the building. He held the door open for her, but as she passed him she felt something brush between the back of her legs. It was his hand, although he claimed it was accidental contact. The investigator felt like the man intended to touch her genitals through her clothes, so it became fourth degree sexual assault.
