The scene of the violence was the medium-security housing facility with seven units, each of which houses about 200 inmates, he said.
Some 80 officers responded to the riot, during which a housing unit was heavily damaged by fire, he said.
California Institution for Men, which opened in 1941, serves as a Reception Center for parolees returning to custody and newly committed male felons from several Southern California counties. The Reception Center completes diagnostic tests, medical and mental health screening, and literary assessments for classification in order to determine inmates’ appropriate institutional placement. CIM houses currently 5,911 inmates and employs approximately 2,100 people.
I should probably add - if anyone has any light to shed about the riot, please do so in the comments.
