The Kosciusko County Sheriff’s Department is warning the public of a scam that has moved to the community again and involves people claiming to be from the IRS. Deputies are investigating a phone scam involving callers who impersonate Internal Revenue Service representatives and demand immediate payments with pre-paid debit cards and wire transfers. The caller often claims the victim owes thousands of dollars in overdue taxes. However, according to the IRS, the agency would always make contact with the taxpayer first by mail or with a personal visit.
