INDIANA -- Indiana State Prison issued a notice Thursday afternoon regarding repeated incidents of inmates tampering with electrical outlets. The prison will remove inmates' personal electrical access in Indiana State Prison's restricted housing unit.

Prison officials say the primary concern is the safety of staff and those in custody, noting that reducing fire hazards is critical. While power to individual cells will be disabled, officials say conditions in D Cell House will otherwise remain largely unchanged. The housing unit's main lights, ventilation system and all wall-mounted commercial fans will remain fully operational.

Indiana State Prison says it is in the process of installing additional lighting to improve visibility.

According to prison officials, inmates will retain access to their personal tablets, which are used for video visits with loved ones and to access entertainment and educational materials. Those devices will be charged via a mobile charging cart.

Inmates who purchased fans from the commissary for added comfort will have them returned once they complete their disciplinary stay and exit restricted housing.
