MOSCOW, January 17 (RAPSI, Lyudmila Klenko) – The Moscow City Court has upheld the extension of detention for Dmitry Buchenkov, who stands charged with participation in the riots on Bolotnaya Square on May 6, 2012, his lawyer Svetlana Sidorkina told RAPSI on Tuesday.

Buchenkov will remain in jail until March 6.

In October, final charges were brought against the defendant. He stands accused of participating in mass riots and attacking persons in a position of authority. There are 6 charge counts and 7 victims in the case against him, Sidorkina said earlier.

Buchenkov pleaded not guilty.

Over 400 people were arrested and scores were injured in the authorized Bolotnaya Square protest that turned violent in May 2012. Dozens were later charged with inciting mass riots and battery against law enforcement officers.

Riot organizers Leonid Razvozzhayev and Sergey Udaltsov were sentenced to 4.5 years in prison each.

Other defendants in the case received prison terms ranging from suspended sentences to four years. Several defendants were pardoned; one is undergoing compulsory mental treatment.
