Six students have been charged as a result of a brawl at Upper Darby High School this month in which a teacher suffered a concussion, township police said Thursday.
As many as 70 students were at the scene - captured on video - outside the school cafeteria, but most were not involved, said Michael Chitwood, the police superintendent.
Charges against the six include simple assault and reckless endangerment. An additional charge of aggravated assault was lodged against Jermaine Richardson, 18, accused of injuring the teacher and the only one charged as an adult.
He was being held at the Delaware County jail on $30,000 bail. The others were sent home. All six are suspended from school, Chitwood said.
