A brawl that erupted at a high school cafeteria in Ohio Tuesday forced police to deploy pepper spray as officials canceled classes for the rest of the day and Wednesday, local media report.

Police handcuffed at least six people at East High School in Youngstown, according to WKBN.

It's not clear what sparked the fight. The school has come under increased scrutiny over trouble disciplining students, The Youngstown Vindicator adds.

Police said they helped get the brawl under control by locking students and staff in classrooms. Some students complained about the pepper spray, but there were no reports of anybody seriously hurt.

Superintendent Steve Stohla told reporters the school would close Wednesday in part to give everyone a chance to calm down. He said it came on the advice of police.

Youngstown is approximately 70 miles southeast of Cleveland.
