Two suspects are in custody following a bank robbery in Shelby County Thursday.Authorities got a call about a robbery at the Elk Horn branch of the Shelby County State Bank, at about 3:30 P.M. Witnesses described the suspect as a white male who appeared to be armed. The man then fled the bank on foot with an undetermined amount of cash, before getting into a blue and silver Chevrolet El Camino. Cass County Sheriff Bill Sage says law-enforcement officers combed roads in the region — “the gravel roads, the secondary roads, the highways, the interstates.” He says a trooper came across a vehicle and arrested two a man and woman without incident, on a dead-end gravel road about two-miles south of Interstate 80, east of highway 71, in northeastern Cass County. The sheriff couldn’t say how much, if any, money was recovered from the scene.
