More than a dozen students at an Austin high school have been charged with misdemeanor rioting for a brawl last month.
Cell phone videos showed no teachers or school administrators present as the students at Eastside Memorial High School were throwing punches and cafeteria chairs at each other.
School district Police Chief Eric Mendez tells The Austin American-Statesman the "quite a bit of chaos" broke out April 9 in the apparent continuation of a fight after school the previous day.
He says teachers were in training sessions at the time and a security guard and school official were responding to another incident elsewhere on the campus.
Authorities say two students also are facing assault charges. One student was taken to a hospital for treatment of minor injuries.
