MOSCOW, September 10 (RAPSI, Diana Gutsul) – Russian opposition activist Leonid Razvozzhayev, who had been sentenced to 4.5 years in prison for participation in the 2012 rallies in central Moscow, filed a complaint with the European Court of Human Rights (ECHR), his lawyer Dmitry Agranovsky told RAPSI on Thursday.

“We have filed a complaint against the inhuman treatment of our client in court and during his transfer to and transportation around Irkutsk and Krasnoyarsk. The complaint also describes an unfair trial and infringements on his rights to defense and the freedom of expression and assembly,” Dmitry Agranovsky said.

Over 400 people were arrested and scores were injured in the authorized Bolotnaya Square protest that turned violent in May 2012. Dozens were later charged with inciting mass riots and battery against law enforcement officers.

Riot organizers Razvozzhayev and Sergei Udaltsov were sentenced to 4.5 years in prison each.

Other defendants in the case received prison terms ranging from suspended sentences to four years. Several defendants were pardoned; one is undergoing compulsory mental treatment.
