Chief of the National Police of Ukraine Khatia Dekanoidze signed an order on Shevtsov's suspension on March 14.
Ukrainian activists earlier claimed that Shevtsov allegedly supported separatism and the annexation of Crimea by Russia, in particular, he participated in the Victory Day parade in Sevastopol on May 9, 2014. Later Shevtsov submitted a document to prove he had successfully passed a lie detector check by the SBU Security Service of Ukraine.
