FARGO, N.D. (AP) – Fargo police are warning residents about a telephone scam with callers portraying themselves as representing “Publisher’s Clearing House” and telling people they’ve won an $800,000 prize.

The caller asks the supposed winners to provide them with a prepaid credit card in the amount of $100 to $150 in order to facilitate the delivery of the prize. Variations of the scam include an additional prize of a new car or other enticements.

Police say that legitimate lotteries and sweepstakes do not require winners to provide payment in order to receive winnings.
