Detention: In annexed Sevastopol on August 14, 2024, FSB officers conducted a search at the home of local 41-year-old resident Tetiana Dyakunovska. After the search, she was taken to an unknown location, and her family did not know her whereabouts for several months.

It was later revealed that she was held incommunicado for several months in Simferopol's pre-trial detention centre No. 2. She was accused of state treason. Details are unknown.

Sentence: As of July 18, 2026, no sentence has been issued. Tetiana Dyakunovska remains in custody. The Russian Federation accuses her under Article 275 of the Russian Criminal Code ('state treason'). Human rights organizations consider the case politically motivated.

Tetiana Volodymyrivna Dyakunovska was born on December 18, 1982. She is a Ukrainian citizen and resident of Sevastopol. There is no confirmed information in open sources about her education, professional activities, or marital status.

On August 14, 2024, FSB officers conducted a search at Tetiana Dyakunovska's residence in occupied Sevastopol. After the search, she was detained on suspicion of 'state treason.' Immediately afterward, all contact with her was lost. Her relatives received no official information about her whereabouts or procedural status.

For the next nineteen months, Tetiana was held incommunicado. Her family repeatedly contacted the police, prosecutor's office, investigative committee, and FSB of Russia with inquiries about her whereabouts. All responses were formal, stating that no criminal cases allegedly existed against her or that the relevant authorities had no information about her location. Human rights defenders equate such practices to enforced disappearance.

Only in the spring of 2026 did human rights advocate Zarema Bariieva report that Tetiana Dyakunovska had been located. It was revealed that she had been unlawfully held in Simferopol's pre-trial detention centre No. 2 all this time. It was then disclosed that Russian authorities officially charged her under Article 275 of the Russian Criminal Code ('state treason'), which carries a penalty of 12 to 20 years imprisonment or life imprisonment.

The Crimean Tatar Resource Center emphasizes that Tetiana Dyakunovska's case is an example of the systemic practice of unlawfully detaining Ukrainian citizens in complete isolation from the outside world. According to human rights defenders, such practices deprive individuals of the opportunity to receive timely legal assistance, maintain contact with their families, and defend their rights. Such cases are increasingly documented in the temporarily occupied territory of Crimea.

As of July 18, 2026, there is no information in open sources about the case being transferred to court, the start of the trial, or the issuance of a sentence. Tetiana Dyakunovska remains in custody, and her case is monitored by Ukrainian and international human rights organizations.
