A red balloon is the calling card of Pennywise, the sewer-dwelling, homicidal clown in "It." The book is set in Derry, Maine. King has said the fictionalized town is based on Bangor. Lt. Tim Cotton joked in the Facebook post that the balloon's discovery was "a little creepy." He says King says he has "no idea" how the balloon ended up behind the secure doors of the police department.
The feature film "It" opened Friday.
