PETERBOROUGH, Ont. - Threats levelled at teachers at a Peterborough, Ont., school have led to charges against a 14-year-old student.

It's alleged the teen threatened to kill a teacher and student teacher at Peterborough Collegiate Vocational School after she was reprimanded Friday.

Police say the girl also spit in another teacher's face.

They say she was found with marijuana at the time of her arrest Saturday and later kicked in the window of an interview room at the police station.

The girl is charged with assault, two counts of uttering death threats, possession of a controlled substance and mischief.

She is scheduled to appear in court today.
