That's when the officer used pepper spray to break it up.
In a letter sent home to parents, Principal Teresa Abron said one shot of the chemical was sprayed. Pepper spray causes tears, pain, and even temporary blindness.
The letter states that most students not involved in the fight had left the room before the chemical was used. An ambulance was called to treat the remaining students who might have been affected.
The letter does not say how many were treated. It does say any who felt discomfort were given a chance to call their parents.
The four students involved in the fight - who weren't named - now face school disciplinary action.
