TECUMSEH, Neb. (AP) – An inmate has been given five to 10 more years behind bars for assaulting a staffer at a southeast Nebraska prison.

Johnson County District Court records say 27-year-old Stephen Knott was sentenced Monday. He’d pleaded guilty. The new sentence will be served after he completes his sentence for false imprisonment, strangulation and other crimes in Platte County.

Prosecutors say the attack occurred July 23, 2017, at the Tecumseh prison.
