Rival street gangs sparked Chino prison melee

December 9, 2009 12:00:00 AM PST
California prison investigators say a feud between black and Hispanic gangs triggered a riot at the California Institution for Men in Chino in August.Two buildings were destroyed in the melee and 240 inmates were injured.

Corrections officials say the riot began with a fight between two Los Angeles County street gangs, one black and one Hispanic. Other inmates joined in the fracas.

Corrections Department spokeswoman Terry Thornton said the gangs were continuing a dispute that began with a smaller fight in May.

Officials plan to ask the San Bernardino County District Attorney's Office to file criminal charges, including attempted murder and battery, against 25 inmates who took part in the melee.

Officials have already charged 222 inmates with rules violations that could lengthen their sentences.
