About

Presumably, Yan Petrovsky is designated as the commander of the Zimargl detachment of the Rusich Group, "one of the special separate units formed for operational and reconnaissance tasks on the territory of Ukraine". According to the US Department of the Treasury, in 2022 he took over as commander of the Group after the leader Alexey Milchakov was wounded near Kharkiv.

Petrovsky was arrested in Finland in July 2023 at the request of the Ukrainian government, who sought to extradite him for war crimes committed during the war in Donbas. The extradition request was rejected due to human rights concerns, but Petrovsky was arrested and charged for the same crimes by the Finnish authorities, who claimed universal jurisdiction over the case. On 14 March 2025 Petrovsky was sentenced to life imprisonment. On appeal this was reduced to 12 and a half years imprisonment.

Arrest and trial in Finland

On 20 July 2023, Yan Petrovsky was arrested by the Finnish police in Helsinki-Vantaa Airport. Ukraine requested the extradition of Yan Petrovsky. The Russian Embassy in Helsinki told RIA Novosti that it had been informed about “the detention of a Russian national in Finland at Kyiv’s request” and that it was “taking measures to provide consular assistance.” Later, Rusich Group announced on its Telegram channel that the task force was halting “any combat missions” until “Slavyan” (Petrovsky) was extradited to Russia.

Petrovsky had entered Finland under the name of Voislav Torden with his wife and three children on 19 July through the Vaalimaa border crossing. According to Petrovsky's lawyer, his intention was that his children "obtain Nordic education" and his wife was already offered a place to study in one of Finnish universities. Petrovsky also visited Finland on tourist visa in 2022 under the new identity of Torden, hoping to visit family in France before they settled in Finland, and Petrovsky was only detained on 20 July in Helsinki airport, shortly before their flight to France. According to Petrovsky's legal counsel, he was only involved in "political activity" in Ukraine but Finnish media referred to a number of interviews Petrovsky gave in Russia, describing his military activities as a combatant during the war in Donbas. In October 2023 the efforts to release Petrovsky from the detainment centre by his lawyers continued, but a Finnish court upheld the decision for him to remain detained until the extradition ruling is made.

The Supreme Court of Finland rejected Ukraine's extradition request, citing "conditions in Ukrainian prisons", ordering Petrovsky's release from Finnish prison on December 8, 2023. He was taken into custody by the Finnish Border Guard, with the Prosecutor General of Finland and Police of Finland looking into the possibility of opening a criminal case against him within the Finnish legal framework on charges of war crimes committed against surrendered Ukrainian soldiers. On 18 December, a Finnish court ordered Petrovsky remanded in custody, pending charges of aggravated war crimes.

The investigation was concluded on 11 October 2024, and on 31 October Petrovsky was formally charged with war crimes. The charges related to a September 2014 ambush against a Ukrainian unit which Petrovsky and several other Rusich soldiers participated in alongside other pro-Russian units. The soldiers had deceived the Ukrainians by raising a Ukrainian flag before attacking them, killing 22 and wounding four. One Ukrainian soldier, Ivan Issyk, had a kolovrat symbol carved into his cheek by the soldiers; he later died of his injuries. Another soldier who was killed during the engagement had pictures of his body posted on social media by Petrovsky himself.

On 14 March 2025 Petrovsky was convicted of four of the five charges against him. He was acquitted of organising the illegal ambush on the grounds that other militant groups had led the operation, but was found guilty of murder, mutilation and publishing degrading images of the dead. Petrovsky was sentenced to life imprisonment, and was ordered to pay compensation to the family of one of the victims. On appeal this was reduced to 12 and a half years imprisonment.
