Law enforcers detained Oleg Kizimenko, who, after the Russian occupation of Crimea, declared himself deputy chairman of the Sevastopol City State Administration, according to  Prosecutor General Yuriy Lutsenko.

"The investigation believes that in this position he contributed to the establishment of the occupation authorities, handed over to the occupiers official documentation, and also contributed to the Russian subversive activities against Ukraine," Lutsenko wrote on Facebook.
