MOSCOW, October 22 (RAPSI) - The Zamoskvoretsky District Court in Moscow on Tuesday refused to release Yaroslav Belousov, one of the persons involved in the Moscow riots case, from detention, his attorney Dmitry Agranovsky told RAPSI on Tuesday.

The court thus rejected a motion filed by Belousov's defense team. Activist's lawyers asked the court to give Belousov and his son Andrei non-custodial sentence because of their health problems.

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.

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.
