MOSCOW, September 8 (RAPSI, Diana Gutsul) - Yaroslav Belousov, who was convicted of participation in Moscow's 2012 Bolotnaya riots and sentenced to 30 months in a penal colony, has been released, his attorney Dmitry Agranovsky told RAPSI on Monday.

After Belousov had his sentenced reduced to 27 months, he filed an application with Moscow‘s Tverskoy District Court to be released on parole.

Belousov, a student of the Moscow State University, was among seven other opposition activists who were convicted and sentenced by Moscow’s Zamoskvoretsky District Court last February.

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

Maxim Luzyanin, Mikhail Kosenko, and Konstantin Lebedev were among the first opposition activists who were sentenced in 2012-2013. Luzyanin, who had pleaded guilty for his role in the riots, was sentenced to 54 months in prison. Lebedev, who also pleaded guilty, got 30 months for having helped orchestrate the Bolotnaya riots. Kosenko was diagnosed with a mental disorder and sentenced to forced psychiatric treatment.

Left Front leader Sergei Udaltsov and Leonid Razvozzhayev were accused of organizing mass protests. They were sentenced last July by the Moscow City Court to 54 months each.
