(Michigan City, IN) - Another inmate at Indiana State Prison in Michigan City has been seriously burned by a fire in their cell.

According to state prison officials, a male inmate was airlifted around 2 p.m. Tuesday. So far, authorities said it appears the inmate tampered with an electrical outlet by jamming bits of metal into the outlet where the fire started.

A few weeks ago, another inmate was severely burned in a fire in their cell.  The same thing has happened to a few other inmates in recent years.

Officials say the state prison is very old and does not have a sprinkler system.
