ST. LOUIS (AP) -- The St. Louis-based utility company AmerenUE is warning customers to beware of con artists seeking personal information.

Ameren says people are calling the company's customers, claiming they are speaking on behalf of Ameren and telling the customers their power will soon be disconnected. The goal of the con artists is to get credit card and bank card information.

AmerenUE serves 1.2 million customers in Missouri and is a subsidiary of Ameren Corp.
