Szergej Vlasenko, a 71-year-old Russian opposition politician living in exile in Poland, was found dead in his Warsaw apartment. Polish prosecutors stated there is currently no indication of foul play, though authorities planned an autopsy and toxicological examination.
Discovery of the Body and Police Investigation
The investigation into the death of Szergej Vlasenko began late Monday into Tuesday as authorities secured the apartment in Warsaw’s Mokotów district (according to reporting from 24.hu). Piotr Antoni Skiba, a spokesperson for the Warsaw district prosecutor’s office, told the Polish news agency PAP that investigators found the politician’s medical documents inside the residence (as detailed by 444.hu).
Local media citing the independent Russian news outlet SOTA reported that Vlasenko had suffered a head injury (noted by origo.hu). His body was discovered by his roommate, who is also a Russian dissident. Reports from the outlet Gazeta indicated that the apartment was locked from the inside, prompting an acquaintance to enter through the balcony to reach the rooms.
Authorities transferred the body to the forensic medicine institute. While initial examinations did not show immediate external signs of violence, officials maintained that only the scheduled autopsy and toxicological tests would establish the definitive cause of death.
Political Exile and Activism in Poland
Vlasenko built a history in public service long before his relocation to Europe. During the 1980s, he served as a local government representative in the Russian Far East. Following the outbreak of the war in Ukraine, he left Russia and settled in Poland, where he was granted political asylum (reported by 24.hu).

In Warsaw, Vlasenko joined the Congress of People’s Deputies. This Russian opposition movement was established in the Polish capital in 2022. The organization’s activities drew swift opposition from Moscow, leading the Russian Prosecutor General’s Office to designate the group as undesirable in 2023 (according to 444.hu).
Differing Perspectives Among Associates
While the district prosecutor’s office emphasized that preliminary findings do not point to third-party involvement, associates close to the late politician view the situation with skepticism. Media coverage highlighted that Vlasenko’s acquaintances suspect a violent death (cited by 444.hu from SOTA). Despite these suspicions raised within dissident circles, prosecutors stated their intent to open an inquiry into suspected involuntary manslaughter while awaiting scientific verification from the forensic examination.

Next Steps in the Inquiry
The timeline moving forward depends on laboratory results. Officials scheduled the autopsy and toxicological analysis to determine the exact sequence of events that led to the politician’s death (noted by origo.hu). Polish authorities continue to investigate the broader circumstances surrounding the case as they await those official findings.
