Czech police in cooperation with the FBI said Wednesday they arrested a Russian national suspected of participating in hacking attacks directed at the United States, officials said.

The suspect, who was not immediately identified, is not linked to recent breaches of the Democratic National Committee, the campaign of Democratic presidential nominee Hillary Clinton or recent cyber incursions of state voter databases that have prompted U.S. authorities to tighten computer defenses across the country, two federal law enforcement officials said.

The officials asked not to be named because they were not authorized to comment publicly.

One of the officials said the suspect is allegedly wanted in connection with a 2012 case involving a private U.S. company located on the West Coast.

"Czech national police announced the arrest of a Russian citizen suspected of conducting criminal activities targeting U.S. interests,'' the FBI said in a statement. "As cyber crime can originate anywhere in the world, international cooperation is crucial to successfully defeat cyber adversaries.''

The FBI said the arrest was related to an international warrant issued through the law enforcement consortium INTERPOL.

Czech police, meanwhile, provided few details about the man's arrest. They said he was detained at a hotel in Prague and subsequently collapsed and was hospitalized for unspecified health reasons. He was not identified and there was no indication when the arrest took place.

U.S. authorities were considering a formal extradition request.

Although the suspect detained in Prague is not believed to be connected to the politically motivated hacks, the U.S. government has said Moscow was behind them. Russian President Vladimir Putin has said his country's interests would not be served by taking part in hacking related to the Nov. 8 presidential election.

Russia is also accused of supplying the WikiLeaks organization with stolen emails belonging to John Podesta, who is chairman of Clinton's election campaign, an allegation that Moscow and the founder of the online leaking platform, Julian Assange, have both denied.

Republican presidential candidate Donald Trump has spoken favorably of Putin, and the Russian leader supposedly favors Trump to Clinton. Relations between Washington and Moscow have soured over the conflct in Ukraine and failed attempts over Syria to find a military or diplomatic solution to the civil war.
