CNN reports that the principal of a New Jersey middle school was stabbed in the chest multiple times by a student while leading a graduation rehearsal on Friday.
They say the student was a 14-year-old boy who has not been identified.
CNN says the student ran across the gym at Union School in Rutherford, New Jersey, and attacked Principal Kurt Scheitzer with a folding knife.
They say the student then turned around, dropped the knife and put his hands in the air.
CNN says both the student and principal were treated for non-life-threatening injuries.
They say the student has been taken into custody and charged with two counts of aggravated assault and two weapon possession charges.
Authorities said police officers will attend the school's graduation as a precaution.
