The suburban St. Louis-based grocery store chain Schnucks now says that 2.4 million credit cards and debits cards of its customers may have been compromised over a three-month period.
Schnucks announced the breadth of the fraud in a statement Sunday. The majority of Schnucks stores are in the St. Louis area, but it operates in five states: Missouri, Illinois, Iowa, Indiana and Wisconsin.
14 News has learned this morning that customers for two local stores, the one on Green River Road in Evansville and the one in Newburgh, could have been affected.
Schnucks advises that if customers suspect their cards may have been compromised, they should immediately contact their credit or debit card company, typically a bank or credit union.
Fraudulent charges have come from around the world.
The company first learned on March 15 of questionable activity and began an investigation on March 19. Schnucks said in pinpointed the problem on March 28 and executed a plan to contain it within 36 hours.
Schnucks says the breach began in December.
