MOSCOW, May 28 (RAPSI) - The Zamoskvoretsky District Court in Moscow has scheduled the hearing on last year's Bolotnaya Square riots for June 6, court spokesperson Yevgenia Pazukhina told RAPSI. The court will hear a case against 12 activists involved in the riots.

"The preliminary hearing will take place behind closed doors, according to the procedure," she added.

According to the Prosecutor General's Office, 82 police officers sustained injuries as a result of the Bolotnaya Square unrest on May 6, 2012 on the eve of Vladimir Putin's inauguration for a third presidential term.

The protest rally ended in violent clashes between protesters and the police. Over 400 people were arrested and scores were injured when protesters briefly broke through police lines in a bid to take their protest to the Kremlin walls.

The Investigative Committee opened a probe against nearly 30 people, including opposition leaders Sergei Udaltsov and Leonid Razvozzhayev.

The criminal case was initiated after the "Anatomy of Protest 2" documentary film was shown on the NTV broadcasting network. The film claimed that the opposition was organizing a coup using funds from abroad and showed Left Front movement coordinator Udaltsov and his companions allegedly talking with Georgian politician Givi Targamadze, who at the time headed Georgia's Parliamentary Defense and Security Committee, and is said to have been involved in planning the "color" revolutions in Georgia and Ukraine, as well as the mass riots in Belarus.

Supporters claim that Udaltsov and Razvozzhayev were framed.

Another defendant - Konstantin Lebedev, who pled guilty earlier to charges relating to the Moscow riots - was sentenced to 2.5 years in prison in April.
