A Lake Ridge Middle School teacher was injured Tuesday taking a knife away from a 12-year-old girl who held it to another girl's throat in class.
The school resource officer was called just before 9:30 a.m. for a student who assaulted another student with a knife while on school property, Prince William County police Master Officer Renee Carr said.
Police say two 12-year-old girls made arrangements to bring a knife to school that day. The student brought the knife and gave it to the other girl, who then then entered a classroom, brandished the knife and held to another 12-year-old girl's neck.
The teacher quickly intervened and was eventually able to take possession of the knife but suffered multiple cuts to his hands, Carr said.
Staff detained the student who had the knife and contacted the school resource officers. The victim reported minor injuries.
Police charged the girl in the classroom attack with aggravated malicious wounding, malicious wounding and possession of a weapon on school grounds, Carr said. She was held at the Prince William Juvenile Detention Center.
