A North Dakota State Penitentiary inmate is accused of choking a prison guard and trying to break his fingers.

Duane Landrus Jr., 42, is accused of choking a guard on March 12 to the point where he could not breathe, then twisting his fingers in an attempt to break them, according to an affidavit. 

Landrus in 2010 pleaded guilty to assaulting a peace officer in Morton County and was sentenced to five years in prison. He is currently serving time for a 2018 conviction for aggravated assault with a dangerous weapon.

Court records do not list an attorney for Landrus on the most recent charge. Authorities on Wednesday issued a summons for Landrus to appear in court, but court documents did not immediately indicate a date.
