Washington ( CNN ) -- An Estonian man was sentenced to seven years in prison on Thursday for his role in stealing more than 240,000 credit card numbers . Aleksandr Suvorov , 28 , had previously entered guilty pleas in two separate schemes . One involved hacking into a computer system belonging to the Dave & Buster 's restaurant chain to steal the credit card numbers of 81,000 customers . The second illegal operation involved a conspiracy to sell more than 160,000 stolen credit card numbers to a buyer in San Diego . The buyer turned out to be an undercover agent with the U.S. Secret Service . `` Computer hackers like Mr. Suvorov victimize businesses and individuals , posing a serious threat to their financial security , '' said Lanny Breuer , assistant attorney general for the Department of Justice 's Criminal Division . `` Suvorov reached across an ocean to victimize thousands of Americans , '' said Loretta Lynch , the U.S. attorney for the Eastern District of New York . Her office prosecuted the Dave & Buster 's case . `` He will now serve his sentence in the country of his victims . '' Suvorov did not work alone in either of the plots . In the one involving Dave & Buster 's he was an accomplice of Albert Gonzalez , a man the Justice Department describes as `` one of the most prolific identity thieves ever prosecuted by the U.S . government . '' Gonzalez received a 20-year sentence in March 2010 for his role in several hacking operations including the one involving Dave & Buster 's restaurants .
