Nikulin was arrested in the Czech Republic on a US warrant in October 2016 for allegedly hacking into computers belonging to LinkedIn, Dropbox and Formspring online services. He was extradited to the United States on March 29.
The Russian Embassy in the United States said it was officially notified by the US State Department about his extradition. Russia's Foreign Ministry said Moscow was outraged by the decision of the Czech Republic to extradite Nikulin.

Nikulin has also been charged with internet fraud in Russia in 2009. Moscow and Washington both requested Nikulin’s extradition on the same day. The Czech court ruled both requests legal, leaving the decision to the country's Justice Minister Robert Pelikan, who satisfied the US request.
Nikulin has previously pleaded not guilty to the US charges against him, which include conspiracy, cyber intrusion and aggravated identify theft.
