On 15 November 2010, Leonid Nikolayev and Oleg Vorotnikov were arrested for overturning seven empty police cars as an art performance act, "Palace Revolution". The official charges were violations of Article 213, Paragraph 1, Item B of the Criminal Code – hooliganism motivated by hatred or hostility towards a social group. No bail was allowed, and the trial was set for 28 February 2011. When bailed out from prison in late February 2011, Vorotnikov skipped on his bail and went into hiding.
