(KLZA)-- A former Tecumseh State Correctional Institute inmate has been sentenced to additional prison time for assaulting an employee at the prison north of Tecumseh. 

28-year-old Kyle Croghan was sentenced to 4 – 6 years by Johnson County District court Judge Rick Schreiner during Monday court proceedings.  

Croghan was an inmate at the prison on October 26, 2016 when he walked around a desk and struck the employee with multiple closed fist blows which caused bodily injury to the employee.  

Croghan's sentence will run consecutively to sentences he is currently incarcerated for, which include numerous charges out of Saunders County and an arson charge in Johnson County. He is currently being held in the Lincoln Correctional Center. 

Deputy Johnson County Attorney Benjamin Beethe was the prosecuting attorney.  The assault was investigated by the Nebraska Department of Corrections.
