Chick-fil-A announced Thursday morning that it is working with law enforcement to look a possible data breach at its restaurants.
In a press release issued by the fast food chain, representatives said they are looking into potential unusual activity involving card payments.
The release did not detail the extent of the possible breach, the number of restaurants or their locations.
The restaurant first learned on December 19 that there was "limited suspicious" payment card activity "appearing to originate from payment cards used at a few of our restaurants."
"We take our obligation to protect customer information seriously, and we are working with leading IT security firms, law enforcement and our payment industry contacts to determine all of the facts," the release read.
Chick-fil-A said it will let customers know more details later, and added that if a breach is substantiated, customers will not be liable for fraudulent charges to their accounts.
Anyone concerned about payment card transactions should call 1-855-398-6439.
