Three inmates were injured when another racially motivated brawl broke out in a jail system wracked by nearly a month of violence, officials said.

The latest fight erupted Monday night at the North County Correctional Facility in Castaic, about 40 miles north of Los Angeles, according to a sheriff's department news release. About 40 black and Latino prisoners squared off in one of the cells of the inmate processing area.

Deputies immediately broke up the fight.

One inmate suffered moderate injuries and was taken to a hospital and two others were treated at the facility for minor injuries.

Two inmates have been killed and more than 100 injured in a series of fights that started in early February at the Los Angeles County jail system.

Until Monday's incident, the violence had ebbed after sheriff's officials isolated ringleaders, took away inmate privileges and transferred some of the most violent inmates to state prisons.
