This was announced by Censor.NET Chief Editor Yurii Butusov on Facebook.
"A source of Censor.NET close to SBU told us that investigation is being conducted against chief of all-arms shooting range of the International Peacekeeping and Security Center. A number of media outlets reported it was head of the Center, Colonel Ihor Slisarchuk, but in fact the searches are conducted not at his place, but at his subordinate's.
"The person suspected of links to Russian military intelligence is the chief of the shooting range, which is a structural unit of the International Center," Butusov wrote.
Earlier, media reported that SBU suspects Ihor Slisarchuk, chief of the International Peacekeeping and Security Center, of cooperation with Russian Main Intelligence Department (GRU) of Russian MoD.
