Working in concert with local authorities,Poor Things the FBI has arrested a Russian man who's suspected of hacking LinkedIn in 2012 and attempting to sell the personal details of users online.

LinkedIn confirmed in an email to Mashable the suspect, who was arrested in the Czech Republic, is allegedly connected to a major breach of the service that affected at least 117 million users.

The true extent of the hack of LinkedIn was made public in a blog post by the company in May. Originally, 6.5 million passwords were leaked online, but this number jumped significantly when a hacker told Motherboardhe had attempted to sell the emails and passwords of hundreds of millions of LinkedIn users on the dark web.

"Following the 2012 breach of LinkedIn member information, we have remained actively involved with the FBI's case to pursue those responsible. We are thankful for the hard work and dedication of the FBI in its efforts to locate and capture the parties believed to be responsible for this criminal activity," a spokesperson for LinkedIn told Mashable.

The FBI has been contacted by Mashablefor comment.

Czech police spokesman Jozef Bocan said the man was arrested in a Prague hotel; the suspect collapsed after being arrested and was then hospitalized. According to the Associated Press, a video of the arrest identified the man as "Yevgeniy N."

The arrest, per another spokesperson, David Schön, was executed several weeks ago but wasn't announced until Tuesday "for tactical reasons," according to the New York Times. The warrant for the arrest was issued by Interpol.

Prague's Municipal Court will now have to decide on his extradition to the United States, with Justice Minister Robert Pelikan having the final say. Spokeswoman Marketa Puci said the court ruled on Oct. 12 that the man will remain in detention until the extradition hearing, the date for which has not yet been set.

Following news of the hack in 2012, LinkedIn urged millions of its users to reset their passwords. When more data breaches were discovered in May, the company invalidated the passwords of any accounts in which users had not reset their password since 2012. The company also encouraged users to implement two-step authentication and to reset passwords for safety.

The announcement of the arrest follows last week's accusations by the Obama administration that Russian hackers were attempting to alter the course of the 2016 presidential election (see: July's hacking of the Democratic National Committee emails and attempts to access various voter registration databases).

The U.S. does not seem content to sit and take it, so to speak: NBC News reported that the CIA is planning a covert cyber attack on Russia in response to the aforementioned hacks, which have been blamed on Russian hackers and are meant to influence the results of the forthcoming U.S. presidential election.

UPDATE: Oct. 19, 2016, 1:23 p.m. EDT LinkedIn confirmed arrest linked to 2012 hack.
