SAUGUS – Shoppers at the Square One Mall on Rt. 1 were evacuated Wednesday evening on a report of a bomb threat.According to Assistant Police Chief Leonard Campanello, a call was placed to Macy’s at approximately 5:45 p.m., by a man with a raspy voice who said a bomb had been placed at the mall. While on the line, Campanello said the suspect asked if he was being recorded, and sounded disappointed when he learned he was not.”He described the specific type of device and he described where he left the device, so we took it as an honest to goodness threat,” he said.The State Police bomb squad was called in, along with three bomb sniffing canines to search the mall, where they remained until a little after 8 p.m.About an hour before the all clear was given, Campanello said two men wearing fake mustaches drove through the parking lot yelling about a bomb, as shoppers and employees huddled together outside.”They may or may not be connected to the threat,” he said. “It’s all very up in the air at this point.”Anyone with information on the incident is urged to call the police at 781-233-1740.
