The U.S. Secret Service and Justice Department announced Wednesday that a founder of one of the world’s most sophisticated Internet sites for trafficking stolen credit card information has been arrested by French police.

Vladislav Anatolieviech Horohorin, 27, was seized at the Nice airport Saturday en route from the Mediterranean principality of Monaco to Moscow, where he resides, authorities said. Horohorin, a citizen of Israel and Ukraine, where he was born, was indicted in November by a federal grand jury in the District on charges of credit card fraud and aggravated identity theft.

The Secret Service called Horohorin one of its five most wanted cyber-criminals in the world. He is part of a “network that has been repeatedly linked to nearly every major intrusion of financial information reported” to international authorities, said Michael Merritt, the Secret Service’s assistant director for investigations.
