Concord - Around noon yesterday, the Walmart store, located in the Supercenter Shopping Center off Dale Earnhardt Boulevard in Concord, reported that two men entered the store to shop. One was carrying a tool box and when a store employee referred them to the customer service desk to get assistance with checking in the box, the question was asked what was in the box? The toolbox carrier made the remark "a bomb." Then the subject left the tool box and entered the main store area to shop. The store clerk contacted the store manager about the comment and the police were called. Store management began an evacuation of about 200 people.
