(AP) — A 36-year-old Grand Island man who was acquitted of murder last year has been given prison time for assaulting a jail guard.

Arkanjelo Kot was sentenced Tuesday to two to four years in prison.

In April a judge denied Kot’s request to withdraw his no-contest plea to assaulting the guard. The incident occurred while Kot was being held in jail awaiting the murder trial.

Prosecutors say Kot punched the guard last June when the guard tried to break up an argument Kot was having with another inmate.

In November Kot was found not guilty of murder in the July 2010 slaying of 17-year-old Walid Omar-Aden. Kot testified that he fired his gun in self-defense.
