Finland's supreme court blocks extradition of Russian terrorism suspect to Ukraine

Finland will not extradite to Ukraine a Russian man suspected of terrorism in Ukraine, Finland's supreme court ruled on Friday, citing the risk of inhuman prison conditions in Ukraine.

Russian national Yan Petrovsky was taken into custody by Finnish authorities in August after a Ukrainian court issued an arrest warrant for the man who is suspected of participating in a terrorist organisation in Ukraine, Finnish court documents seen by Reuters showed.

Social media channels linked to Russia's Wagner Group mercenaries said in August that Petrovsky was a top fighter in Rusich, a far-right subunit affiliated to Wagner.

Rusich identified Petrovsky as a founding member and leader of the unit who has been under European Union and United States sanctions since last year.

In Finland, Petrovsky has used the name Voislav Torden, court documents showed.

"The Supreme Court has stated in its opinion today that the extradition request regarding Torden cannot be agreed to," the court said in its decision.

It cited an earlier decision by the European Court of Human Rights which found Ukrainian prisons overcrowded and materially deprived over long term, concluding extradition to Ukraine could lead to inhuman and degrading treatment for Petrovsky.

The court ordered Petrovsky to be released but he was immediately taken into custody by the Finnish Border Guard.

"Following a decision by the chief investigator, we have taken the person into custody ... and we are investigating the conditions for his presence in the country," Deputy Commander Mikko Hirvi of the Gulf of Finland Coast Guard told Finnish news agency STT.

An official in Ukraine's General Prosecutor's office, said Kyiv would press requests for Petrovsky's extradition.

"We are continuing to seek ways of detaining and extraditing this suspect to Ukraine," Andriy Gulkevych, deputy head of the office's international legal section, told national television.

"Under our legislation, he remains a suspect. "We have sent the appropriate requests for his arrest and extradition."

Gulkevych said Ukraine was working towards ensuring greater success for its extradition requests, often turned down on grounds that the country could not provide suitable conditions of detention while it is at war.

Petrovsky, who was previously a resident of Norway, is a long-time far-right activist who helped found Rusich as an explicitly neo-Nazi unit during the opening stages of the conflict in the Donbas in 2014.
