MOSCOW, March 27 (RAPSI) – Prosecutor has asked Moscow's Zamoskvoretsky District Court to send the Bolotnaya Square riot case defendant Maxim Panfilov to a specialized hospital for compulsory medical treatment, attorney Sergey Panchenko told RAPSI on Monday.

Defense in turn insisted on ambulatory treatment of Panfilov at the place of residence.

Sentencing of the defendant has been scheduled for March 29.

Earlier, the term of Panfilov’s detention was extended until June 14, 2017.

On April 8, 2016, the Basmanny District Court in Moscow ordered the detention of Panfilov. The day before, he was charged with participation in mass riots and use of violence against a law enforcement officer. According to investigators, the accused snatched a helmet off a riot policeman’s head on May 6, 2012.

Investigators believe that Panfilov suffers from chronic personality disorder.

The march on Yakimanka Street and the rally on Bolotnaya Square in May 2012, both authorized by the officials, resulted in mass riots and clashes with the police. Dozens of people were injured, over 400 protesters were detained.

The riot organizers, Sergey Udaltsov and Leonid Razvozzhayev, were sentenced to 4.5 years in prison. Other participants received prison terms from suspended sentences to four years. Several defendants were pardoned; one was sent for compulsory mental treatment.

The convicts’ supporters believe that the riots were provoked by police.
