McAfee software creator jailed in Spain, sources say

John McAfee, an anti-virus software creator indicted for fraud in the United States, was in jail on Tuesday pending extradition procedures after being arrested in Barcelona airport at the weekend, sources said.

The McAfee software founder was detained on Saturday when about to board a flight to Istanbul with a British passport, a Spanish police source said.

A judicial source said McAfee was then presented to a high court judge through a video call and sent to prison without bail where he will await the extradition process.

A third source, from the Catalonia region's justice department, said he was in the Brians 1 jail, which opened in 1991 in an industrial area 45 minutes by car from Barcelona. Some local politicians have been jailed there for corruption.

After he was arrested, McAfee's official Instagram account posted a "Free McAfee" message with a photo of him. The person running the account did not return a message seeking comment.

No other representatives were immediately contactable.

US federal prosecutors unsealed an indictment on Monday against McAfee over charges that he evaded taxes and wilfully failed to file returns.

That came shortly after the Securities and Exchange Commission revealed it had brought civil charges against McAfee, alleging he made over $23.1 million in undisclosed compensation from false and misleading cryptocurrency recommendations.

He is alleged to have earned millions in income from promoting cryptocurrencies, as well as through consulting work, speaking engagements, and selling the rights to his life story for a documentary.
