The State Department of Correctional Services reports the three were taken to a local hospital, where they are being treated for non-life threatening injuries. Corrections has not released names.
According to a news release from Corrections, preliminary reports indicate an inmate from SMU West struck the staff member escorting him late this afternoon. Three other inmates joined in the assault. Two staff members responded.
Corrections locked down the SMU West unit after the fracas, pending investigation of the incident by Corrections investigators.
The SMU West unit is a maximum-custody general population unit housing 100 inmates.
All other housing units at Tecumseh and facility operations remain under normal conditions.
The Tecumseh prison was the scene of a riot last May 10th that left two inmates dead.
