 Shoppers were unable to enter or leave the South Williamson Walmart for a brief time Monday when the store went on lockdown after receiving some type of threat. It happened around one o'clock Monday afternoon, resulting in the store locking its doors. Kentucky State Police tell Mountain Top News that they investigated the threat and determined it to be a hoax. Shortly after police arrived on the scene, the store reopened its doors and customers were allowed in and out once again.
