An employee at the Salem Crossing Walmart took the first threatening call sometime before 12:30 p.m., and evacuated the store out of an abundance of caution, police said. The threat was believed to be unsubstantiated.
Then, a call was placed to the store on Virginia Beach Boulevard. While that call was also believed to have been unsubstantiated, a heavy police presence was at the store the remainder of the day.
The FBI was helping to identify the caller, police said.
