Detention: On April 20, 2021, Russian security forces detained Yevhen Petrushyn, a resident of occupied Sevastopol. The following day, the unlawful 'Leninsky District Court of Sevastopol' ordered his detention until June 19, 2021. On April 22, the FSB of Russia released a video of the detention, claiming Petrushyn allegedly collected and transmitted information about the activities of the Russian Black Sea Fleet to the Main Intelligence Directorate of the Ministry of Defense of Ukraine. Russian authorities charged him under Article 275 of the Russian Criminal Code — 'treason.' Ukrainian human rights advocates emphasize that Russia's application of this article to residents of occupied Crimea results from the unlawful imposition of Russian citizenship and violates international humanitarian law. In June 2021, Yevhen Petrushyn was unlawfully transferred from Sevastopol to Moscow, where the Lefortovo Court repeatedly extended his detention.

Sentence: On December 19, 2022, the Russia-controlled 'Sevastopol City Court' sentenced Yevhen Petrushyn to 12 years in prison under Article 275 of the Russian Criminal Code — 'treason.' According to the Russian FSB, in 2020–2021, he allegedly transmitted information about the activities of the Russian Black Sea Fleet to Ukrainian intelligence. The details of the case, evidence, and Petrushyn's position are not disclosed in open human rights materials.

CrimeaSOS considers Yevhen Petrushyn's case as politically motivated persecution of Ukrainian citizens in occupied Crimea.

Yevhen Petrushyn was born on December 21, 1998. At the time of his detention, he was 22 years old. He lived in Sevastopol, in the territory temporarily occupied by Russia. Other biographical details such as education, profession, marital status, and family are not provided in priority open sources and are therefore not included as unverified data.

According to the Russian FSB, in 2020–2021, Petrushyn allegedly collected and transmitted information concerning the activities of the Russian Black Sea Fleet to Ukrainian intelligence. The Russian side claimed that this information allegedly constituted state secrets, and its transmission could harm Russia's defense capabilities. Based on these allegations, a criminal case was initiated against him under Article 275 of the Russian Criminal Code.

On April 20, 2021, Petrushyn was detained by Russian security forces. The following day, the unlawful 'Leninsky District Court of Sevastopol' sanctioned his arrest. On April 22, the FSB released a video of the detention, accompanied by claims about Petrushyn allegedly transmitting information to Ukrainian intelligence.

In June 2021, Yevhen Petrushyn was transferred from Sevastopol to Moscow. He was held in the Lefortovo pre-trial detention center. In July 2021, the Lefortovo Court in Moscow extended his detention until September. Human rights advocates considered this persecution illegal and emphasized that transferring residents of occupied Crimea to Russia violates international humanitarian law.

On December 19, 2022, the occupation 'Sevastopol City Court' sentenced Petrushyn to 12 years in prison for 'treason.' According to CrimeaSOS, the sentence is among those issued as part of politically motivated criminal prosecutions of Crimea residents.

He is held in Correctional Colony No. 11 in Kirovo-Chepetsk, Kirov Oblast, Russian Federation, serving a 12-year sentence under Article 275 of the Russian Criminal Code. As of September 9, 2026, no updated information on a change in his place of detention is available in priority sources.
