A collection call center in Mason City, Iowa was evacuated Tuesday after the office received a threat by telephone, according to local paper the Globe Gazette.
IC Systems was forced to clear their 200 employees out of the office when an unknown person called and stated, ?You have six minutes to get out of the building,? operations manager Scott Bultje told the Gazette.
Bultje said that they did not believe the threat was real but they evacuated anyway for the safety of their employees. Police searched the building and found nothing threatening.
Employees returned to work shortly after the police left.
