MOSCOW, August 6 (RAPSI) - The lawyers have asked the Zamoskvoretsky district court of Moscow to place nine suspects standing trial on charges of having organized riots in Bolotnaya Square on May 6, 2012, under house arrest, lawyer Dmitry Agranovsky told RAPSI Tuesday.

According to Agranovsky, the motion is connected with a previous ruling of the Moscow City Court to release Nikolai Kavkazsky, who has been charged with participation in mass protests in central Moscow in May 2012. On August 2, Kavkazsky was placed under house arrest.

Nine defendants are currently in the remand prison. Two individuals, Nikolai Kavkazsky and Alexandra Dukhanina have been placed under house arrest. Maria Baronova, who is also a suspect in the case, has been earlier released, but restricted.

The mass protests took place at a Moscow protest rally on the eve of Vladimir Putin's inauguration for a third presidential term in May 2012. The rally ended in clashes between protesters and the police.

Over 400 people were arrested and scores were injured when protesters briefly broke through police lines.

Russia's Investigative Committee opened a probe against nearly 30 people, including opposition activists Sergei Udaltsov and Leonid Razvozzhayev. The former was charged with organizing riots involving violence, arson, the destruction of property, the use of fire arms and explosives, lawyer Dmitry Agranovsky told RAPSI in June.

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.
