The riot broke out Wednesday shortly after 11 a.m. inside a yard at the prison. One of the injured inmates was shot by a correctional officer, and at least 12 others were taken to the hospital after being stabbed or slashed during the riot.
Prison officials said 60 inmates were involved. There was no word on what sparked the riot.
According to a statement released by a prison representative, officers tried to quell the riot by firing non-lethal rounds. They also fired six shots from a rifle. The use of potentially deadly force is under investigation, which is standard procedure.
This marks the second known incident within a year at the maximum-security facility. In December, 11 inmates were hospitalized, including one shot by officers, after a riot that involved 150 inmates. One officer was injured during the confrontation.
