MOSCOW, August 1 (RAPSI) - The Basmanny District Court has extended Left Front leader Sergei Udaltsov's time under house arrest until October 6, RAPSI reports from the courtroom on Thursday.

The court has thus upheld the investigators' motion. Udaltsov's attorneys have appealed to replace his house arrest with travel restrictions.

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.

Udaltsov is being prosecuted as a result of a probe into the circumstances portrayed in the highly controversial "Anatomy of Protest-2" documentary film. The film claims that Udaltsov and his supporters planned to stage mass riots and a coup using funding from the Georgian leadership, which has long been at odds with President Vladimir Putin's government.
