Los Angeles ? Los Angeles County jail officials separated black and Hispanic inmates, began transferring troublemakers out and brought in clergy to try to restore peace after a week of racially charged brawls.

Thousands of Hispanics and blacks clashed Feb. 4, and a black inmate was beaten to death, at the biggest jail at the Pitchess Detention Center.

Originally, investigators believed Hispanic gang leaders outside the jail ordered the first fight as retaliation for a street attack, but that proved untrue.
