10 Students Arrested on Felony Mob Action Charges After Brawl Outside of Rich South High School

Ten students are facing felony mob action charges after a brawl outside a suburban Chicago high school.

Authorities say three students were injured at Rich South High School as a fracas erupted Monday between students from the school and Rich Central High.

Officials say about 1,400 Rich Central students were bused to Rich South after a bomb threat. While they were waiting in the gym, someone pulled a fire alarm, sending about 2,800 students from both schools outside.

That's when fights erupted. It took more than two dozen police officers about an hour to control the crowd.

All the teenagers are charged in juvenile court except for one. District 227 Superintendent Doris Langon says more charges are expected.

School board members say their emergency plan had been approved by police.
