TECUMSEH, Neb. (AP) — Authorities say four staff members were injured by two inmates at the Tecumseh prison in southeast Nebraska. The melee occurred Saturday when an inmate refused a cell search and appeared to dump homemade alcohol into a toilet. Authorities say the staffers used pepper spray on him when he wouldn’t let them into the cell, and another inmate punched a staffer. The inmates kicked, punched and kneed staffers before being restrained. Authorities say the four staffers were taken to a hospital and treated for scrapes and bruises. One was diagnosed with a concussion.
