The North Carolina school district is investigating a dispute involving a parent and several teenagers who beat up a 14-year-old girl inside her classroom.
The incident, which was filmed on a cellphone video and posted on social media, took place on Tuesday at Southern Guilford High School in Greensboro.
Janson Silvers, a spokesman for Guilford County Schools, said a teacher and other staff members, as well as police, had intervened to resolve the dispute.
The unidentified 14-year-old girl suffered minor injuries.
Guilford County Sheriff Captain Brian Hall told NBC's WRAL staff in Raleigh that a mother and 37-year-old teenagers arrived at the school in two cars. He said the fight was in retaliation for Monday's altercation at a school bus stop, according to the site.Authorities have not identified the mother or any of the teenagers who attacked the girl. They were all caught and face charges of misdemeanor assault and inciting a riot, according to WRAL. Those who aren't students of Southern Guilford may also face first-degree trespassing charges, Hall told the outlet.

The incident happened after the first bell rang, meaning all doors to the school were locked. Silvers said the school was following proper safety regulations.
The group was able to enter the building as it was leaving another person who was not involved, he said. A student from Southern Guilford High School was ready to take the group inside and lead them to the victim's classroom.
Three of those involved in the incident are students from Southern Guilford, according to Silvers. He said any regional student who participated in the fight would face disciplinary action.
Authorities did not identify the mother or other youths who attacked the girl. All were arrested on charges of assault and disorderly conduct, according to WRAL. Non-Southern Guilford students may also face the first criminal charges, Hall told the area.
"My first feelings are just sadness, honestly," the captain told WRAL. "That students believe that's the right way to deal with their problems with each other, but that they'll think school is the right place to do that."
