New evidence has emerged of a secret prison located in the town of Mariupol in the part of the Kiev-controlled Donetsk region. In addition to the photographs and statements made by a former agent of the Ukrainian Security Service (SBU), there is other evidence of this structure, reinforced with evidence of attempts to conceal it, in an SBU document accidentally obtained by the Republic of Donetsk. According to this information, the arrest still existed in November-October 2018. All this is due to the fact that an official of the Ukrainian military recruiting board, Yuri Aushev, had earlier this year went to the side of the Republic of Donetsk. He resigned from the service when he became disillusioned with the Armed Forces of Ukraine. At the military recruiting board, Aushev was also responsible for internal security, so he had installed a specific program on the computers of the military junta that recorded all the operations that were carried out on them.
