Northern Illinois police say residents have reported sightings of scary clowns.
They occurred in areas such as DeKalb and Rockford and mirror similar reports coming in from across the country since late August.
Rockford police say most reports have been unfounded, with the exception of one dressed for a radio promotion.
DeKalb police officer Craig Woodruff says there were two reports late Tuesday night. One allegedly fled the scene when spotted by passerby, but the other was reportedly riding a bicycle in a costume.
