(KNZA)--A bench trial has been set for a Doniphan County Sheriff’s deputy, facing charges pertaining to his alleged mistreatment of a suspect.

Raymond Hall pleaded “ not guilty” last week in Doniphan County District Court to misdemeanor charges of mistreatment of a confined person and battery.

A bench trial was set for April 18.

Formal charges were filed against Hall last November, with the complaint naming James Groh as the victim in the case.    

According to Doniphan County Sheriff’s Office arrest documents, Groh was arrested by Hall in Wathena on June 22, 2017 for assault on a law enforcement officer and interference with a law enforcement officer.

Hall remains free on a $2,500 bond.

Nemaha County Attorney Brad Lippert is serving as special prosecutor in the case.
