MOSCOW, January 18 - RAPSI. Alexander Dolmatov, who was one of the defendants in the case over the Bolotnaya Square riots which occurred on May 6 last year, has committed suicide in Amsterdam, his lawyer Yevgeny Arkhipov has told RAPSI.

"Geert Ates, director of the United for Intercultural Action refugee network, told me that Alexander Dolmatov, who had requested political asylum in the Netherlands in 2012, committed suicide in a refugee center in Amsterdam last night. I do not know the reasons for his suicide or any other details," the lawyer said.

Mr. Arkhipov said a court hearing on Dolmatov's appeal against the refusal to grant him asylum was to be held in the next few days.

Clashes with the police flared up on May 6 during an officially sanctioned opposition march in Moscow. Dozens of protesters and police officers were injured. The police detained over 400 rally participants. After May 6, the opposition continued its protests as "people's promenades," as crowds of opposition activists strolled peacefully through the city in a show of opposition.

The Zamoskvoretsky District Court in Moscow has already sentenced Maxim Luzyanin, another suspect in the case, to 4.5 years behind bars. The court is also considering the prosecutors' request to apply compulsory medical measures against suspect Mikhail Kosenko.

Investigative Committee spokesperson Vladimir Markin stated earlier that separate proceedings in the case have been initiated against 12 suspects, who are familiarizing themselves with the case's materials.
