An old scam resurfaced in the Bulloch County area Thursday, with callers threatening to sue victims if they didn’t pay back taxes.Both the Bulloch County Sheriff’s Office and Statesboro Police Department, as well as Bulloch County 911, fielded numerous calls Thursday about suspicious calls from people claiming to be with the Internal Revenue Service.While most people are aware of whether or not they are in arrears with tax payments, many become confused and frightened and succumb to the demands. Callers ask victims to send money orders or put money on prepaid cards to make the false payments.Tom Lavender received such a call, listening to it as a recorded message on his answering service. It sounded so real, it alarmed him at first, he said.“I broke out in a sweat,” he said.
