Buckeye Check Cashing of California recently began notifying an undisclosed number of customers that their personal information may have been accessed following a recent robbery.

According to the notification letter [PDF], a laptop containing customers' names, addresses, bank account information and/or Social Security numbers was stolen from a locked vehicle in a "smash-and-grab type of theft" on June 27, 2013. Credit cards, a wallet and other personal property were also taken from the vehicle.

"The removal of any laptop containing the personal information of our customers was against our company's data security policy and the involved employee has been reprimanded," the company stated in the notification letter [PDF]. "We have no reason to believe that this type of incident would occur in the future."

All those affected are being advised to place fraud alerts on their credit files, and are being offered a free one-year membership in Experian's ProtectMyID Alert service. Customers with questions are advised to call (855) 327-1712.
