The Russian national who was accused by American officials of hacking U.S. targets and arrested earlier this month in the Czech capital is 29-year-old Moscow resident Yevgeny Nikulin.
Czech authorities this week said the suspect was detained October 5 in downtown Prague in response to an Interpol warrant requested by the United States, and he now faces a Czech extradition hearing, according to RFE/RL's Current Time TV.
Current Time's investigation uncovered Nikulin's Instagram account under the handle "i.tak.soidet," displaying a taste for luxury cars and jewelry and a digital trail that led through Belarus and Poland to the Czech Republic in the weeks before the Prague arrest.

The Instagram account went private shortly after Current Time's Russian-language report was published October 20. Soon after that, Russian Foreign Ministry spokeswoman Maria Zakharova confirmed Nikulin’s identity for journalists in Moscow.
"The Russian Foreign Ministry and the Russian Embassy in Prague are actively working with the Czech authorities to prevent the extradition of a Russian citizen to the United States," she added.
The detention of Nikulin shows Washington is mounting a global manhunt against Russian citizens, Zakharova said Thursday, Reuters reported.
LinkedIn hack
Hours after news emerged of Nikulin's arrest, the professional networking service LinkedIn issued a statement suggesting the development was connected to a 2012 breach of its members' information. In May, LinkedIn acknowledged that intrusion compromised more than 100 million of its users' passwords.
No date has been set for Nikulin's extradition hearing, but Czech authorities said the man would remain in custody until that process.
The Russian Embassy in Prague told Current Time that Moscow will be seeking his return to Russia. Moscow, an embassy source said, rejects "the U.S. practice of forcing the entire world to enforce its extraterritorial jurisdiction."
Interpol had issued a so-called Red Notice for the alleged Russian hacker, a designation for "wanted international fugitives."
