Corrections investigates after an inmate is hospitalized after being assaulted by another prisoner at the Lincoln Correctional Center.
The Nebraska Department of Correctional Services reports the inmate received a "puncture wound" to the chest during a fight on Monday.
Investigators say a homemade weapon believed to have been used during the assault was recovered inside a trash can.
It had been passed to a third inmate, who threw it away.
Staff also recovered a bag inside the same trash can, thought to contain homemade alcohol.
The housing unit where the assault happened was placed on modified operations to allow for additional interviews with witnesses.
Results of the investigation will be provided to the Lancaster County Attorney for determination of criminal prosecution.
The Corrections disciplinary process will be utilized with sanctions, such as loss of good time, applied according to the rules and regulations.
