GREEN BAY -- Neighbors in Green Bay, Wisconsin are on edge after seeing a person dressed like a clown on the city's streets Tuesday evening.

The pictures are going viral on Facebook. The original post has almost 8,000 shares. A Facebook page has also been created to post future sightings of the clown, called Gags - The Green Bay Clown.

Police say they've received a few calls about the clown. 

"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," said Captain Kevin Warych with the Green Bay Police Department.

Police say their options are limited in dealing with the situation.
