ORONO — Police in Orono say four people arrested for trespassing in the late-night hours told them they were hunting for ghosts and had brought along a camera in hopes of documenting paranormal activity.

Orono police Officer Wilfred King says two men and two women between 19 and 25 were issued summons shortly after midnight Tuesday. The four allegedly ignored no-trespassing signs and scaled a barbed-wire-topped gate leading to Ayers Island in the Penobscot River, where textile and paper mills once operated.

The Bangor Daily News says local legend has it that the island is haunted by the ghost of a mill foreman who was killed in a mysterious accident, and the ghost of a young girl whose father accidentally killed her after being tricked by a 300-year-old American Indian curse.
