Investigators of the Main Investigation Department of the National Police, together with operatives of the Department of Strategic Investigations, with the assistance of the Main Intelligence Directorate of the Ministry of Defense of Ukraine, identified the command staff of the 83rd Separate Air Assault Brigade and an FSB lieutenant colonel involved in the torture of residents of Dymer in 2022.
From February 24 to March 31, 2022, russian forces temporarily occupied the settlement of Dymer in Vyshhorod district of Kyiv region. The occupation grouping included units of the 83rd Separate Air Assault Brigade. On March 21, 2022, criminal proceedings No. 42022112330000083 were opened regarding the events in Dymer under Parts 1 and 2 of Article 438 of the Criminal Code of Ukraine (violation of the laws and customs of war).
In particular, on the premises of the Viknaland enterprise at 22-B Vyshneva Street, the occupiers set up a site for the unlawful detention of civilians. A key role in crimes against civilians in Dymer was played by the FSB “curator” of the 83rd brigade, Lieutenant Colonel Sergey Oleynichuk.
He was directly involved in the so-called “filtration” — interrogations of detainees accompanied by torture, cruel treatment of civilians, and hostage-taking. Oleinychuk could make decisions on the deportation of detained local residents to the territory of russia. In total, Ukrainian law enforcement documented the illegal transfer of at least 42 persons. Civilians were held in penal institutions and pre-trial detention centers, including colonies and detention facilities in Rostov, Mordovia, Bryansk, Smolensk, Perm, Tula, and Vladimir regions. Some of them were later returned. However, at least 24 civilians remain in captivity.
The materials concerning Oleynichuk have been separated into a separate proceeding. He has been notified of suspicion of violating the laws and customs of war, accompanied by cruel treatment of civilians. The sanction of the article provides for punishment of up to life imprisonment.
