The St. Peter Police department is investigating several incidents of debit card fraud. Numerous St. Peter residents have reported that their cards were used to make unauthorized purchases in different states, and even in a different country. All of the victims still possess those debit cards, however, but investigators have learned that the cards had all been used at the same retailer, meaning that a third-party card processor may be responsible for the fraud. There have been similar cases of fraud reported in other communities around the area also. Anyone who notices any unauthorized transactions on their cards should contact law enforcement to help prevent similar cases in the future.
