Zimin was arrested on June 8, 2012 and has been kept in the No5 pre-trial detention prison. He is accused of participating in mass riots (paragraph 1, article 212 of the Russian Criminal Code) and of using force against a representative of the authorities (paragraph 1, article 318 of the Russian Criminal Code). He is facing up to thirteen years in prison. Zimin was accused of throwing a piece of asphalt at a Special Unit policeman that allegedly broke the policeman’s finger. Medical experts concluded that the finger could not have been broken due to such action and that the injury was more likely a result of twisting.
On November 27 the students of the RGHU organized a picket in support of Stepan Zimin.
