The Liberation Movement shared footage showing the abduction of Lytvynenko.

"Both are charged with some kind of an attack in Kirovograd region, but they are taken to the known destination – to an investigator of the Donetsk police, Artem Podvih [in Mariupol, Donetsk region]. It was him who has managed to secure the arrest of Oleksandr Novikov, a war veteran from the Donbas Battalion (nom de guerre "Hammer"), in a court hearing behind closed doors today," MP Yegor Sobolev wrote on Facebook on Sunday evening. "Friends, they can seize them, as most of people in Ukraine are now keeping silent or think they are 'gangsters.' They all – 'Hammer,' 'Gal' and 'Bek' – were among the organizers of the camp of the Liberation Movement on Hrushevsky Street [in Kyiv], where we came out in demand for the adoption of anti-corruption laws."

Sobolev called on Ukrainians to join in activists of the camp. "We are inviting all those who are against the transformation of our country into the 'DPR' [self-proclaimed 'Donetsk People's Republic'] to a general gathering at 19:00 tomorrow [Monday, November 27]," he added.

Another MP Semen Semenchenko posted footage how police together with a riot unit were blocking Liberation Movement activists outside Kyiv not letting them enter the city.
