According to Montclair police and Montclair High School Principal Joshua Cho, the disturbance in the fourth quarter was caused by students possibly fighting on the south side of the stadium on Orchard Street, and a weapon was believed to be involved. About 1,500 people were in attendance at the game, all of whom left in a mass panic, police said.

Video posted to social media of the halted game show people hurrying to leave the bleachers and at least one person jumping a fence. At least one post to Twitter claimed the incident was a shooting with one person dead and three hospitalized.

The Ontario High School team and their cheerleaders were bussed back to their school, and Montclair’s students were released to their parents, Cho said.

One person suffered a medical emergency during the incident, but Chaffey Joint Union High School District Superintendent Mat Holton said it was not due to any injury sustained during the panic. He also said that no gun or other weapon was fired or seen.

“Many students and attendees understandably were panicked and frantically left the area,” Holton said in his statement, that was tweeted out Saturday. “MPD is aware of the fight which sparked this entire incident and is investigating all leads…including posted online videos.”
