A grand jury has indicted more than two dozen people over their alleged involvement in a northwestern Missouri prison riot.

Missouri Attorney General Eric Schmitt announced the charges Tuesday. They stem from a May 2018 protest-turned-riot at Crossroads Correctional Center in Cameron.

Prison officials say more than 200 inmates staged a sit-down protest over restrictions on recreation and programs that were borne out of a corrections officer staffing shortage. Close to 80 allegedly refused to return to their cells and damaged property until a Highway Patrol negotiator brokered peace about six hours later.

The grand jury issued charges related to violence against other inmates, damage to prison property and tampering with a motor vehicle for allegedly operating a forklift unlawfully.
