According to WJLA:

A large Metro station brawl between students from two D.C. high schools was caught on camera Friday.

It happened around 4 p.m. at the Gallery Place-Chinatown Metro station. Officials say it was a result of an ongoing rivalry between students from McKinley Tech and Woodrow Wilson high schools.

A Metro spokesperson says Metro Transit Police were tipped off about a possible incident during a conference call before the fight.

Because the brawl was so large, more police officers were called for backup.
About six juveniles were arrested.
