Alliant Utility Scam in Northern Iowa

MASON CITY, Iowa (AP) — Mason City police are warning residents and business owners of a phone call scam in which someone is pretending to be with a utility company.

The city's police department says it's received a report of a caller posing as a representative with Alliant Energy.

The impostor told a local business on Monday that its account was delinquent. The caller wanted the business to buy a pre-paid credit card and provide its information over the phone.

Alliant Energy doesn't ask customers to purchase prepaid credit cards.

Anyone receiving a similar call is asked to contact authorities.
