ST. LOUIS (KSDK) - A tip from a viewer alerted us to possible credit card fraud for some customers who shop at Schnucks supermarkets.
NewsChannel 5 called Schnucks to find out more.
In a statement, the grocery chain told us it's working with credit card companies to investigate reports of fraud.
Schnucks says it's in the process of gathering information from all of its partners in the credit card process, and that could take some time.
In the meantime, Schnucks recommends customers report any unusual account activity to their card providers.
