The Union County State’s Attorney’s office is warning residents about a telephone scam.

State’s Attorney Tyler Edmonds says someone is contacting residents, saying they are from Ameren and the resident owes a specific amount of money for unpaid electric bills. The caller then demands payment by credit card over the phone.

Edmonds says anyone who feels like they may have been targeted should contact the Union County State’s Attorney’s office at 618-833-7216 or the Union County Sheriff’s office at 618-833-5500.
