PHILADELPHIA (CBS) — Investigators say 10 students were taken into custody after a massive brawl at Overbrook High School in West Philadelphia.

The brawl, which was captured on cell phone video, allegedly began over a post on social media.

The incident was reported at about 10:15 a.m. Monday in a third-floor hallway.

As a result of the incident, two students suffered minor injuries. A school administrator also suffered a minor leg injury.

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

Workers and parents of students at the school believe recent cuts in school personnel have left the school too understaffed to be safe.

However, a Philadelphia School District spokesperson disagreed with that sentiment.

“We’re seeing an increase in incidents at this school this year. The good news is we have actually more police staff at this school this year than last year,” School District spokesman Fernando Gallard said.

Only three hours after the initial brawl, the unidentified school worker captured cell phone video of students running across tables in the cafeteria to witness another fight.

“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,” said the worker.

School officials say the students involved in the brawl were suspended.

The high school was placed on lockdown.
