A St. Charles woman reported to police Nov. 29 about receiving a voice mail message from someone claiming to be with the IRS who said the resident owed $2,000 in back taxes and needed to call a phone number to transfer the owed money to avoid an arrest warrant in her name, said Officer Bill Tynan. The phone call is the first one associated with what authorities call the "IRS Phone Scam" to be reported to St. Charles police in six months.
