Officials are investigating two separate incidents where staff members were attacked by an inmate at two Nebraska prisons.
A Nebraska Department of Correctional Services staff member at the Nebraska State Penitentiary was assaulted by an inmate Monday.
While two NDCS staff members at the Lincoln Correctional Center were assaulted by an inmate on Tuesday.
Officials said Monday's incident at NSP began when the staff member attempted to talk to a visibly agitated inmate in an effort to de-escalate the situation.
The inmate began striking the staff member with closed fist punches. Physical force was used to subdue the inmate.
The staff member was transported to a local medical facility for treatment of non-life-threatening injuries and released.
Officials added that Tuesday's incident at Lincoln began when staff members, also attempting to de-escalate an agitated inmate, were struck by closed fists punches from the inmate.
Physical force was used to subdue this inmate as well.
Both members were transported to a local medical facility for treatment of non-life-threatening injuries and released.
"The names of the staff members and inmates will not be released and an investigation is underway. Assault on Nebraska Department of Correctional Services staff will not be tolerated," Officials said in a statement.
NDCS officals say they will investigate the incident and submit their findings to the local county attorney for prosecution.
