Who’s riding around on their bike slapping people’s butts in Denver?

Do this in a baseball dugout, no problem. Do it to a random woman on the street, BIG problem.

A serial butt-slapper is on the loose in Colorado. Cops are asking people to help identify him.

A woman in the Denver suburb of Lakewood was out jogging on New Year’s Day when he drove up behind her on an e-bike and slapped her butt.

Then a day later, he did it again to a different woman in the same area. (Same area meaning same part of town . . . but yeah, also on her butt.)

At least two other incidents have been reported so far.  Someone got a shot of him on his e-bike, but you can’t see his face.

A serial butt-slapper might sound funny, but seriously, he could face sexual assault charges.
