(Anamosa, IA) -- Anamosa State Penitentiary is on restricted movement while a search for contraband is conducted.
Two inmates were found unresponsive in their cells and given Narcan Sunday night after a similar incident Saturday night where three staff members were exposed to an unknown substance while administering Narcan to another unconscious inmate.
The Iowa Department of Corrections says the two cases are unrelated but both will be investigated, and no visitors are allowed at the prison until restrictions are lifted.
