Spanish police have arrested a Russian programmer for alleged involvement in “hacking” the US election, Spanish press reports say.
Pyotr Levashov, arrested on 7 April in Barcelona, has now been remanded in custody.
A “legal source” also told the AFP news agency that Mr Levashov was the subject of an extradition request by the US.
The request is due to be examined by Spain’s national criminal court, the agency added.
El Confidencial, a Spanish news website, has said that Mr Levashov’s arrest warrant was issued by US authorities over suspected “hacking” that helped Donald Trump’s campaign.
Several cybersecurity experts, including Brian Krebs, have also linked Mr Levashov to a Russian spam kingpin, who uses the alias Peter Severa.
