Kansas City, Kansas police say a bomb dog did a sweep of the Walmart and found nothing after a man called in a bomb threat on Sunday afternoon.
The Walmart near the Legends Shopping Center was initially evacuated after the threat but was re-opened after the building was cleared.
Officials say a man called KCK police and said he put a bomb in the store and was sitting in a white van outside. Police did find a man in a white van parked outside the store but determined he had nothing to do with the call.
Police are still trying to determine who made the call and are treating it as a credible threat. The building is still being searched and a K-9 unit has been called in.
