TULSA, Okla. – If you visited a popular Chinese restaurant in the last year, your personal information may be at risk.

P.F. Chang’s announced that credit and debit card information may have been stolen from 33 restaurant locations.

The majority of the restaurants that are affected are in California, but there are others scattered across the United States.

Officials say the P.F. Chang’s restaurant, located at 1978 E. 21st St. in Tulsa, was on the list.

The company says it first found out about the data breach in June.

However, the time frame for the potential thefts date as far back as October 2013.

In a news release, P.F. Chang’s said, “We have reason to believe that the intruder may have stolen some data from certain credit and debit cards that were used during specified time frames at 33 P.F. Chang’s China Bistro branded restaurant locations in the continental United States. The potentially stolen credit and debit card data includes the card number and in some cases also the cardholder’s name and/or the card’s expiration date. However, we have not determined that any specific cardholder’s credit or debit card data was stolen by the intruder.”

P.F. Chang’s announced that it will provide free identity protection services for those who have been affected.

It says that guests can have the credit bureaus place a “fraud alert” on their files, which alerts creditors to take additional steps to verify their identity before granting credit in their names.
