MOSCOW, May 27 (RAPSI) - A criminal case against 12 people suspected of provoking mass unrest in Moscow on May 6, 2012 has been filed with the Zamoskvoretsky District Court in Moscow, the court's press secretary Yevgenia Pazukhina told RAPSI Monday.

Some of the suspects are accused of taking part in the riots, while the others are charged with use of force against police.

As the investigation into the criminal case against protesters is underway, more suspects are expected to show up in court.

According to the Prosecutor General's Office, 82 police officers sustained injuries as a result of the Bolotnaya Square unrest.

The mass riots took place at a Moscow protest rally on the eve of Vladimir Putin's inauguration last May for a third presidential term. The 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 proceedings into the mass unrest against nearly 30 people, including opposition leaders Sergei Udaltsov and Leonid Razvozzhayev.

The case was inititated 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 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.
