Ten students from Overbrook High School in West Philadelphia were taken into custody after a massive fight broke out, according to a report from CBS.

The fight was captured on cell phone video and allegedly began because of a post on a social media site, the report said.

Two students suffered minor injuries, the report said, along with a school administrator.

An employee at the school who asked not to be identified told CBS that this type of behavior isn’t uncommon.

“It’s mayhem. Students are in the hall, they’re smoking in the bathroom; cigarettes, marijuana,” the worker said. “We can’t contain them and it’s really hazardous for us working and these kids are not being educated at all.”

This same worker captured a cell phone video of students running across cafeteria tables to witness another fight that occurred three hours before.

“It’s a zoo in here. Parents really need to come up here and see what’s going on in this school because it’s ridiculous,” the worker told CBS.
