FOX19 - Scarier than a scene from IT with Pennywise the Dancing Clown - imagine one walking around your neighborhood in the dead of the night.
The first sighting happened Monday around 2 a.m., according to a Facebook page called "Gags – The Green Bay Clown."
Green Bay, Wisconsin police said they have received several calls about the mysterious clown, but said what they're doing is legal.
"A person can walk down the sidewalk dressed however they want as long as they're in a place they legally can be, and they're not in a place that has a closing time, like a park," Captain Kevin Warych with the Green Bay Police Department told WGBA-TV.
According to commenters on the Facebook page, this could be a recent shoot of a scary movie.
