In April 1993, members of the Aryan Brotherhood along with members of the Black Muslims and other gangs in the Southern Ohio Correctional Facility initiated the Lucasville Prison Riot in Lucasville. The rioters took several officers hostage and killed nine inmates, then killed an officer. Their complaints included alleged abusive treatment and overcrowding, with Black Muslims also demanding an end to mandatory tuberculosis testing, which they said violated their faith.[19]
