Spanish authorities have detained a pro-Russian Ukrainian blogger and aspiring politician on an international arrest warrant for suspected treason, a police source told Reuters today.

The source said Anatoliy Shariy, a vocal critic of Ukrainian President Volodymyr Zelenskiy and his pro-Western government, had been detained in the coastal city of Tarragona in Catalonia, the source said, without providing further details.

Earlier, Ukraine's SBU security service said in a statement Shariy was detained on Wednesday in an operation coordinated between Ukrainian authorities and Spanish police on suspicion of committing treason and the crime of "breaching the equal rights of citizens" based on race, nationality or other attributes.

"SBU investigators consider that Shariy carried out unlawful activity detrimental to Ukraine's national security in the information sphere. There are reasons to believe that Anatoliy Shariy acted on orders of foreign bodies," it said.
Ukraine declared Shariy a suspect a year before Russia's invasion of its neighbour on Feb. 24.

After his investigative reports featuring frequent criticism of Ukrainian authorities led to problems with the law and following an attempt on his life, Shariy has lived in self-imposed exile in the European Union since 2012: first in Lithuania, then in the Netherlands and in Spain's Catalonia region.

Shariy, 43, has taken a particularly pro-Russian stance since the 2014 Maidan uprising in Ukraine and Russia's annexation of Crimea.

A frequent guest on Russian state TV channels, he supported the Kremlin's narrative of Ukraine being a Western "colony" dominated by Russian-hating neo-Nazis in his videos, justifying the invasion and accusing the Ukrainian media and Zelenskiy of manipulating public opinion in the West.

In 2019, he registered a Ukrainian political party, called The Party of Shariy, which won a few dozen seats in several regional assemblies.

Ukraine's National Security Council suspended the party, along with several others linked to Russia, in March following Russia's invasion.

Last month, the Spanish authorities seized the Russian superyacht, Tango, which is moored at the Real Club Nautico in Palma. The vessel was searched by police and members of the FBI were also involved in the operation.

Tango is owned by Viktor Felixovich Vekselber a Ukrainian-born Russian–Cypriot billionaire, and businessman. He has an estimated wealth of 10 billion dollars and is said to be a close friend of Russian friend Vladamir Putin.Vekselberg is chairman of Renova, the investment group that has a stake in United Co. Rusal, Russia's biggest aluminum producer. The Bahamas-based company also owns shares in equipment makers Sulzer and Oerlikon. He owns regional airports in Russia and sold 12.5% of a Russian oil venture for $7 billion in 2013.
