The 14 year old girl accused of injuring several people in a knife attack at Dunbarton High School in Pickering is facing more charges.
Two new charges of assault with a weapon were added to the 15 charges she was already facing when she appeared in court this morning.
The teen was already facing charges including assault causing bodily harm, assault and possession of a dangerous weapon.
Durham police said the new charges were laid after investigators reviewed surveillance evidence from the school.
The girl was taken into custody after a series of attacks Feb. 23 at Dunbarton high school. Witnesses reported a girl armed with two knives made her way through the hallways, slashing at victims before she was restrained by staff members.
Five students and two staff members were hurt but none of the injuries were life-threatening.
The girl, who appeared by video, is due back in youth court March 15.
