Firefighters wheel away one man from Muir High School during lockdown following reports of a big brawl on campus.
Details are few at the moment, but John Muir High School is on lockdown following reports of a "brawl," according to the police scanner.
Ambulances took away two men -- one from inside the school, and one near the corner of Lincoln Avenue and Idaho St. which may or may not be related to the lockdown.
Official word is sketchy right now, but neighbors suggested the brawl may have occured because of ethnic or gang tensions on campus.

Earlier, an Hispanic man was also taken away by ambulance across the street in an incident that may or may not be related.
Pasadena police and sheriff's deputies -- some armed with large rifles -- stand by the school's main entrance.
About 20 police and sheriff's vehicles responded to the school, as well as the Pasadena police helicopter, a handful of motorcycle units, and fire engines and ambulances.
