Three teenage girls have pleaded guilty to assault after a brawl at a Pennsylvania school injured seven staff members, including a teacher who suffered a concussion trying to break up the fight.
The Philadelphia Inquirer reports the girls, ages 15 and 16, will be sentenced June 1. Another 18-year-old student is also charged in connection with the fight.
Prosecutors say the brawl at Cheltenham High School, in Wyncote, Montgomery county, continued even as a teacher lay unconscious on the ground.
Lawyers for the teens say they had never been in trouble at school or with the law before.
