Authorities were trying to determine whether excessive weight was to blame for the collapse of a stage during a performance at Servite High School in Anaheim on Saturday night, injuring about two dozen students.
About 250 girls from Rosary High School, Servite's sister Catholic school, were on the stage when it collapsed, Anaheim Police Department spokesman Lt. Tim Schmidt told The Times.
"Early investigations suggest the front of the stage gave out due to weight," Schmidt said. The Anaheim Fire Department was on the scene soon after the incident, trying to determine the cause of the collapse.
Schmidt told the Orange County Register they were checking to see if the permit for the stage included a weight limit.
Officials said most of the injuries were "minor to moderate," though some students suffered broken bones.
