BEATRICE - Nebraska corrections officials say a staff member of the Tecumseh State Prison was assaulted by two inmates Thursday, resulting in serious injuries.

The staff member was escorting one of the inmates back to a cell shortly after 6:30 p.m. The wrong door was mistakenly opened and a second inmate, armed with a homemade weapon, stabbed the staff member multiple times. The first inmate kicked the staff member in the head.

Three additional prison staffers responded, securing the inmates and providing aid to the injured staff member. The injured employee was taken to Johnson County Hospital in Tecumseh, where he received stitches and was released.

Authorities are investigating the incident and will turn over information to the Johnson County Attorney for possible charges.
