An Oahu grand jury has indicted a former Halawa prison inmate for allegedly causing serious bodily injury to another inmate on Dec. 22.

The Attorney General’s Office announced Tuesday that Julius Mitchell, a former inmate at Halawa prison, was indicted on first-degree assault for injuring Kevin Nakayama, another Halawa inmate.

A bench warrant was issued for Mitchell’s arrest. His bail was set at $25,000.

Department of Public Safety Director Nolan Espinda said the department “does not tolerate violent acts committed by offenders. This indictment is a result of our collaboration with the Attorney General’s Office to crack down on criminal behavior and we will continue to work with them as they investigate and prosecute cases such as this one.”
