MADISON, Wis. (AP) -- Video posted on the popular Internet Web site YouTube.com helped Madison School District officials identify four girls involved in fights at a middle school.

Administrators say in addition to the four girls involved in the two fights, the person who recorded the confrontations could face discipline.

District spokesman Ken Syke says district policy prohibits recording students without their consent.

Syke says the students involved in the Toki fights could face suspension or expulsion, depending upon the outcome of school investigations.

The school district recently added a second security guard and dean of students at Toki because staff and parents were concerned the school was becoming too chaotic, including incidents of fighting, profanity and disrespect.
