A food fight erupted at Minneapolis South High school Thursday which escalated into a brawl involving hundreds of student and injuring several.
Staff called the police to break up a fight consisting of more than 200 students, which forced the school into a partial lockdown, the Los Angeles Times said.
When the police arrived they demanded the students to disperse. When the students did not listen, the officers sprayed mace in the air causing students to flee from the area, the Los Angeles Times said.
One staff member and three students were taken to the hospital for medical attention.
Although school district officials said they did not know what sparked the fight, parents and students believe it is the increasing racial tensions between Somali-American students and the others, the Star Tribune said.
Officers will review the surveillance cameras and charges will be filed from there, the Los Angeles Times said.
