A bomb threat call was received at 2:00am this morning, to the Walmart on Sigmon Road. More than a dozen people were immediately evacuated from the store. The store manager and security did a sweep of the inside. Wilmington police conducted a search on the outside of the building. Nothing suspicious turned up from the search. Everyone was let back into the building within an hour, after the store manager was given the okay from the general manager. The call is still under investigation.
