MITCHELL, S.D. (AP) — Authorities have a suspect in custody in an armed robbery at a laundry business in Mitchell.

Police Sgt. Dean Knippling tells The Daily Republic that a suspect was arrested about seven hours after the holdup at Plaza Cleaners about 3:30 a.m. Wednesday.

The suspect was arrested for an unrelated reason and wasn't immediately charged in the robbery.

Authorities say a male with a handgun held up Plaza Cleaners early Wednesday, then also tried to rob a person near another business as he fled the scene. No one was hurt in either incident. Schools in the area were locked down during the search for the suspect.
