The Mississippi corrections commissioner says part of one state-run prison is on lockdown because of a staffing shortage.

Commissioner Pelicia Hall says in a news release that visitation and other privileges are also canceled indefinitely at that prison, the South Mississippi Correctional Facility in Leakesville.

Hall said Friday that the prison was holding 3,051 inmates - 31 short of capacity. The staffing vacancy rate there is 48 percent.

Movement is restricted in a part of the prison that houses more than 1,800 inmates. Other parts of the prison have normal operations.

She says lockdown also could be used at two other state prisons, if needed. She says staffing vacancy rates are 46 percent at Central Mississippi Correctional Facility and 42 percent at the Mississippi State Penitentiary at Parchman.
