The Nebraska Department of Correctional Services says an inmate at the Reception and Treatment Center in Lincoln assaulted a staff member resulting in serious injury.
They say the assault happened Saturday afternoon when the staff member was escorting the inmate from a holding cell to a restroom and back again.
Corrections says the inmate refused to return to the cell and punched the staff member in the face.
The staffer was able to control the inmate until fellow guards removed him from the area.
The injured staff member was treated at the hospital for a broken nose.
An investigation has been launched, and findings will be provided to the Lancaster County Attorney for possible charging decisions.
