Detention: The exact date of detention is not disclosed in open sources. The persecution became known in 2023.

Sentence: As of July 17, 2026, information about the sentence is not available in open sources. According to human rights defenders, Serhiy Horyunov is one of the Ukrainian citizens persecuted by the Russian Federation for alleged participation in the Crimean Tatar volunteer battalion named after Noman Çelebicihan.

Serhiy Horyunov is a Ukrainian citizen who became the subject of criminal prosecution by the Russian Federation in a case concerning alleged participation in the Crimean Tatar volunteer battalion named after Noman Çelebicihan.

Open sources provide almost no biographical information about Serhiy Horyunov. There is no disclosed information about his birth date, place of residence, education, profession, or marital status. Such secrecy is typical for many criminal cases initiated by Russia against Ukrainian citizens.

The Russian Federation systematically uses Article 208 of the Russian Federation Criminal Code (“Participation in an illegal armed formation”) to prosecute Ukrainian citizens. The occupation authorities cite alleged participation in the Crimean Tatar volunteer battalion named after Noman Çelebicihan, which was declared a “terrorist organization” by the Russian Federation Supreme Court in 2022, as the basis for such criminal cases. Human rights defenders emphasize that a significant portion of those persecuted are civilians, and the evidence of their guilt often does not meet international fair trial standards.

Due to the closed nature of the investigation, confirmed data on the circumstances of Serhiy Horyunov's detention, his place of detention, the course of the investigation, or the trial are not available in the public domain. Information about his health status, access to a lawyer, or the ability to maintain contact with family is also not disclosed.

As of July 17, 2026, no new officially confirmed information regarding Serhiy Horyunov's procedural status has been disclosed in open sources. His case remains among the documented instances of persecution of Ukrainian citizens on charges of alleged participation in the battalion named after Noman Çelebicihan.
