Detention:In September 2024, in occupied Sevastopol, FSB officers detained 66-year-old local resident Nina Tymoshenko. Following her detention, she was placed in a pre-trial detention centre and criminal proceedings were initiated under Article 275 of the Criminal Code of the Russian Federation for 'state treason'. The exact date of detention is not specified in available human rights sources.

Sentence: On March 21, 2025, the occupation Sevastopol City Court found Nina Tymoshenko guilty under Article 275 of the Criminal Code of the Russian Federation and sentenced her to 16 years in a general regime colony, a fine of 200,000 rubles, and 1 year of restricted freedom after release. On May 13, 2025, the Third Court of Appeal of General Jurisdiction upheld the sentence. On February 24, 2026, the Supreme Court of the Russian Federation also upheld the sentence, making the decision final.

Nina Ivanivna Tymoshenko was born on April 13, 1958, in the Zakarpattia region of Ukraine. She spent most of her life in Sevastopol. At the time of her detention, she was 66 years old and a pensioner.

After the occupation of Crimea in 2014, Tymoshenko remained living in Sevastopol.

Before her detention, she lived in Sevastopol and was a pensioner.

According to the Russian investigation, in September 2022, Tymoshenko allegedly contacted the 'hotline' of the Main Intelligence Directorate of the Ministry of Defense of Ukraine and offered assistance. The Russian side claimed that later, in October – November 2023, she transmitted information about military facilities of the Ministry of Defense of the Russian Federation, as well as photos and videos of Black Sea Fleet ships, to a representative of the Ukrainian special service via messenger. These claims represent the position of the Russian prosecution.

In September 2024, Tymoshenko was detained by FSB officers in Sevastopol. She was charged under the article for 'state treason'. After her detention, she was placed in a pre-trial detention centre. Subsequent court proceedings were held in closed session.

On January 24, 2025, the criminal case against Tymoshenko was submitted to the occupation Sevastopol City Court. The case was presided over by Judge Igor Kozhevnikov. According to 'Crimean Process', this judge had previously issued verdicts in other politically sensitive cases involving residents of occupied Crimea.

On March 21, 2025, Tymoshenko was sentenced to 16 years of imprisonment. In addition to the main punishment, the court imposed a fine of 200,000 rubles and one year of restricted freedom after release. This is one of the longest sentences given to women from the occupied territories of Ukraine on similar charges.

On May 13, 2025, the Third Court of Appeal of General Jurisdiction in Sochi upheld the sentence.

On February 24, 2026, the Supreme Court of the Russian Federation denied the cassation appeal and upheld the sentence. According to 'Crimean Process', the case was accompanied by significant coverage in Russian media, while the position of the convicted or her defense was hardly represented.

Human rights defenders also emphasize the illegality of applying Russian law in the occupied territory of Crimea and the systematic use of 'state treason' charges to persecute peninsula residents.

As of September 13, 2026, the last confirmed place of detention for Nina Tymoshenko is IK-28 of the Federal Penitentiary Service of Russia in the Volgograd region, in the city of Leninsk.
