GREAT FALLS, Mont. - A 14-year-old Great Falls boy believed to have attacked a teacher at North Middle School faces a Youth Court charge of attempted kidnapping.

The boy made an initial court appearance Wednesday and his bail was set at $50,000.

Prosecutors allege the boy put on a hooded sweatshirt and a ski mask after school on Tuesday and grabbed the teacher from behind while holding a tissue across her face. She was able to break free from the boy's grip and he fled.

The Great Falls Tribune reports officers found the boy's backpack in a trash can. It contained belts, a necktie, strips of fabric and photographs of females being tied up and forcibly restrained.

The school's resource officer says surveillance video helped identify the boy and locate his backpack.
