Since July 15, the activists have been gathering at the Solovki Memorial Rock – a monument to victims of Soviet labor camps that sits across from the former KGB headquarters, Lubyanka – in support of Taisiya Osipova, the wife of Other Russia party bureau member Sergei Fomchenkov. Osipova was arrested last November under charges of drug possession, which she and her supporters insist was planted by officers from the Center for Extremism Prevention (Center “E”) in an attempt to exert pressure on her husband.

On Monday, four activists from Solidarity and the Other Russia party were added to the total number of Lubyanka detainees.

“The police detained four activists who attempted to jump over the barricade” that had been erected to prevent protesters from reaching the monument, explained Other Russia member Matvei Krylov.

At least the majority of the detainees spent the weekend in police holding facilities. All are charged with disobeying police orders, an offense punishable by up to 15 days of administrative arrest.

Nevertheless, the protesters intend to hold their ground until July 21, when a court is set to rule on Osipova’s case.

That officials from Center “E” might attempt to frame a person associated with the Russian opposition should come as no surprise: the controversial Internal Ministry operation has been blamed by human rights groups internationally for harassing, beating, kidnapping, and torturing “criminal suspects,” who often include peaceful political, environmental, and artist activists.

The Center raided an apartment where Fomchenkov, Osipova, and their child were present in December 2009 without explaining the basis for their actions.

According to National Bolshevik member Sergei Yezhov, Center “E” officials attempted for several hours to enter an apartment on Volgogradsky Prospect, but the residents refused to open the door as the officials would not state the purpose of their visit.

Present in the apartment at the time was National Bolshevik and member of the executive committee of the Other Russia coalition Sergei Fomchenkov, and National Assembly deputies Taisiya Osipova, Margarita Filippova, Mikhail Klyuzhev, Nikolai Medvedev, and Maksim Gromov, as well as an infant child.

The apartment is currently undergoing a search.

A second apartment owned by Aleksandr Averin, press secretary for National Bolshevik leader Eduard Limonov, was broken into by Center “E” officials that same afternoon.

Officials detained Averin and his apartment is also currently being searched.

Gromov had arrived in Moscow to attend a meeting with Heidi Hautala, chairman of the European Parliament’s Subcommittee on Human Rights. He stated that the legitimacy of the activities of Center “E” was to be a topic of discussion during the meeting.

The Center for Extremism Prevention is accused by Amnesty International of stifling dissent from journalists and activists under charges of extremist activity; a 2009 report cites accusations of torture to extract confessions from criminal suspects. In November, members of the opposition Solidarity movement obtained an internal memo indicting Center “E” in the illegal detentions of a number of activists. Solidarity leaders are planning to use the document in a criminal suit against the center.
