The Alabama Department of Corrections is investigating an assault on a corrections lieutenant that was reported Thursday at the William C. Holman Correctional Facility in Atmore.

The assault occurred inside the prison at about 1 p.m. when the lieutenant was attempting to control the inmate who was making threatening remarks to other corrections officers.   The inmate assaulted the lieutenant with a makeshift weapon causing injury.    

The lieutenant was transported to a local hospital where he was listed in stable condition.  No other inmates or officers were involved in the incident.

Inmate Robert Washington, 27, is being charged with the assault.  Washington is serving a 20-year sentence on a 2010 first-degree robbery conviction out of Montgomery County.

This is the second assault on a corrections official at the prison since September.  Corrections Officer Kenneth Bettis was stabbed on Sept. 1. and later died of his injuries.

A Corrections Emergency Response Team (CERT) will remain at the facility to augment the prison’s security staff.   The prison is locked down while ADOC investigates the incident.

Corrections officials are not releasing the lieutenant’s name at this time.
