Last week, the Pennsylvania State Police issued a bulletin warning residents about the possible return of “creepy clown” sightings due to the movie upcoming release.

“With the fall of 2017 upon us, it is anticipated that similar ‘creepy clown’ sightings could be reported starting as soon as September, in part due to the fact that the movie ‘It’ will be released in theaters on 9/8/2017,” the bulletin reads. “The movie, which is adapted from a Stephen King novel by the same name, portrays an evil demon who takes on the shape of a clown named Pennywise, ‘that stalks kids from within the sewers and killing them when they least expect it.’”
