Warrants were issued for four North Carolina high school students after a school administrator suffered a concussion in a violent fight at the institution, Fox-46 reported Friday.

Police in Charlotte, N.C., issued four warrants after students were caught on tape attacking Harding High School administrator Annette Albright. The station confirmed that one alleged participant in the melee was 15 and another was 16. Authorities have not yet released their identities.

Albright told the station the 15-year-old female student slapped her face after threatening her. She said the student was among a group that was skipping class and she was called to make sure the they went to their session.

She said the student, who had recently returned from an alternative school after being involved in another violent attack, became enraged when Albright radioed the school’s resource officer for backup.

The girl said “I was calling the cops on her brother,” Albright told the station.

Footage of the fight was posted to Facebook, but was later removed.

No students have yet been charged.
