FRANKLIN, Ind. (AP) — A suburban Indianapolis prosecutor has pleaded guilty to criminal confinement and other charges for allegedly injuring a woman his home.

State police say Johnson County Prosecutor Brad Cooper pleaded guilty Monday in Hancock County to criminal confinement, identity deception, official misconduct and domestic battery.

Under state law, the convictions remove Cooper from office. Indiana Prosecuting Attorneys Council spokesman Zach Osowski says Cooper’s chief deputy prosecutor will serve as acting prosecutor until a Republican caucus picks a new prosecutor. Cooper has been prosecutor since 2009.

Court documents allege Cooper struck a woman and confined her without consent on March 4 at his Trafalgar home. He also allegedly pretended to be the woman in electronic messages he sent to someone else.

Online court records didn’t list an attorney for Cooper.
