Mitchell’s Walmart was evacuated for around 45 minutes on Friday morning due to a bomb threat.  At around 9:40 AM, dispatch received a call from a Mitchell Walmart employee reporting they received a call from someone claiming there was a bomb in the store.  The store was immediately evacuated by law enforcement.  Shortly after responders arrived, it was learned that other Walmart stores in South Dakota received similar calls this morning.  The store was checked by law enforcement, and it was found to be a prank call.  Officials are working to identify the source of the call, but it appears to have originated outside the Mitchell area.  Mitchell Police, the Davison and Hanson County Sheriff’s Offices, and Mitchell Fire and EMS responded to the threat.
