Minneapolis school officials say they take seriously concerns about a "possible racial component" to a fight involving hundreds of students at South High School.
In a statement, Minneapolis Public Schools says the district and police continue to investigate the cause of Thursday's lunchroom brawl that sent four people to hospitals with minor injuries.
The district says South operated on a normal schedule Friday, under a precautionary lockdown. Students remained in their classrooms at all times, and access into and out of the building was limited. Additional safety and security measures also were in place.
A Minneapolis police spokesman says the case has been turned over to investigators.
South plans to host a parent and community meeting soon.
Police used chemical spray to break up the melee. No one was arrested.
