The Janesville Mall deals with a second bomb threat in less than a week. Janesville police say a threat was made Wednesday night through social media. A similar threat was made Saturday night. Shoppers, however, were not told to evacuate Wednesday night like they were Saturday, when the first bomb threat was made through a message, posted on the mall Facebook page, indicating explosives had been placed at the mall. Police say officials were lead to believe the threat was not credible.
