MOSCOW, November 6 (RAPSI) - The Moscow City Court on Wednesday upheld a previous court decision to extend the house arrest of Left Front leader, opposition activist Sergei Udaltsov, RAPSI reports from the courtroom.

The court thus rejected an appeal filed by Udaltsov's attorneys who asked to replace activist's house arrest with travel restrictions or release him on bail.

On October 2, Moscow's Basmanny District Court granted the investigation's motion to extend the house arrest of Left Front leader until February.

Udaltsov has been accused of organizing riots and using violence against police during a rally on May 6, 2012 in Moscow's Bolotnaya Square and organizing mass riots in Russia. In October 2012, he was ordered not to leave the city. On February 8, investigators requested to have him placed under house arrest, as he allegedly violated the former ruling.

The criminal case in 2012 May 6 riots 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.
