Crimean Tatar Enver Mamutov, who was sentenced to almost 17 years in prison, was transported from IK-11 in Stavropol Krai to IK-3 in the Chuvash Republic. This is another 1,500 kilometers away from home, which creates difficulties for visits with relatives.

According to Mamutov's wife, he spent five days in a punishment cell in May. His lawyer was forbidden to visit him under the pretext of holding a meeting in the Stavropol colony.

Enver Mamutov was sentenced to 16 years and 9 months under Part 1 of Article 205.5 of the Criminal Code of the Russian Federation ("Organization of the activities of a terrorist organization"), as well as Part 2 of Article 35, Part 1 of Article 30, and Article 278 of the Criminal Code ("Preparation for the violent seizure of power by an organized group by prior conspiracy").

Bakhchisarai residents Zevri Abseitov, Rustem Abiltarov, Remzi Memetov and Enver Mamutov were detained on May 12, 2016. The group of Crimean Tatars was accused of involvement in the Islamic political party Hizb ut-Tahrir, which is banned in Russia but operates freely in Europe and most countries around the world. According to the case materials, the convicted persons did not have weapons or ammunition, did not plan to commit a terrorist act and did not call on others to commit terrorist acts.

According to human rights activists, the alleged members of Hizb ut-Tahrir are being prosecuted not for preparing a coup d'etat and terrorism, but for participating in public actions against political repression in Crimea and criticizing the Russian authorities.
