LIMON |  Corrections officials say an inmate at an eastern Colorado prison assaulted and injured a guard.

The Colorado Department of Corrections said in a statement on Friday that inmate Ryan Spear “seriously assaulted” a correctional officer at the Limon Correctional Facility.

The department says other prison staffers were able to restrain Spear. The statement says the officer was treated at a hospital but the injuries were not life-threatening.

The guard was not identified.

Spear, who is 29 and has been in prison since 2010, was transferred to another facility.
