Four potential participants in the march for the federalization of Siberia that did not take place in Novosibirsk, Alexei Baranov, Konstantin Eremenko, Alexander Atabaev and Stanislav Karakovsky, were interrogated as part of a pre-investigation check based on materials transferred by the FSB to the Investigative Committee. According to Baranov, after the interrogation, Karakovsky was taken away by employees of the "E" center in an unknown direction. Further procedural steps in relation to the rest are also unclear, but according to Baranov, they were hinted that they would be taken for further interrogations, probably to the “E” center. All four are now in the status of detainees, their phones were confiscated from everyone except Baranov, information was written off from them under the pretext of "search for extremist materials."
