A man booked into the Clackamas County Jail on identity theft charges is part of a larger investigation into credit card fraud.

Eduard Kholstinin is one of 17 people and a corporation indicted on more than 173 charges of identity theft, worldwide trafficking in stolen credit card numbers and other crimes committed using the Internet.

According to prosecutors, Kholstinin worked with a group known as the Western Express Cybercrime Group out of Manhattan.

The 17 suspects, prosecutors said, developed a computer program that would tap into the Internet and obtain credit card information.

Over a four-year period, from 2002 to 2006, Kholstinin and other stole more than 95,000 credit card numbers and racked up more than $4 million in charges.

Prosecutors said the defendants ran Internet ads saying they had countless credit card numbers and other identifying information to sell to crooks.

Nine of the suspects have been arraigned in a New York court. Kholstinin and one other defendant are being held outside of New York on unrelated charges.

Prosecutors said there are six people still at large.

It is unclear when Kholstinin will be extradited to New York City to make a court appearance.
