The 27-count indictment was returned March 12 and unsealed Monday in Central Islip, N.Y.

The indictment charges Maksym Yastremskiy of Kharkov, Ukraine, and Aleksandr Suvorov of Sillamae, Estonia, with wire fraud, computer fraud and identity theft charges. The third man, Albert Gonzalez of Miami, was charged with one count of wire fraud conspiracy.

The two Eastern European men allegedly gained access to cash register terminals at 11 Dave & Buster's restaurants by installing a "packet sniffer," a code to capture data, at each restaurant.

At just one restaurant, information on 5,000 credit and debit cards was captured, eventually causing $600,000 in losses for the financial institutions that issued them, the indictment alleged.

Yastremskiy was arrested in Turkey in July 2007, and remains there pending Turkish charges. The department said a formal request for extradition has been filed. At U.S. request, Suvorov was arrested in March 2008 by German officials, and remains there pending extradition. U.S. Secret Service officials arrested Gonzalez in Miami earlier this month.
