Anton Tsvetkov, a member of the Moscow Public Observer Commission, will probe the statement made by opposition activist Leonid Razvozzhayev saying he was tortured during his detention in connection with a criminal case involving preparations of mass riots.

"I take this information under my personal control. Today, or tomorrow at the latest, my deputy or myself will meet with Razvozzhayev in the establishment where he will be placed and we will ask him about it," Tsvetkov told Interfax on Monday.

Vladimir Markin, an official with the Investigations Committee, told Interfax earlier on Monday that Razvozzhayev had testified that the mass riots that occurred in the Moscow Bolotnaya Square on May 6 were financed by Givi Targamadze, former head of the Georgian parliament's committee on defense and security.

Left Front leader Sergei Udaltsov told Interfax the report by the Investigations Committee "is either misinformation or they forced Razvozzhayev to testify against himself, maybe under torture."

The day after information on Razvozzhayev's detention was reported, a video of police officers leading Razvozzhayev out of the court building was posted on the Internet. When Razvozzhayev saw journalists, he shouted: "Tell them I was tortured! I was tortured for two days, I was abducted in Ukraine!."

"On October 21 Razvozzhayev himself contacted the Main Investigative Department of the Investigative Committee and said he was willing to turn himself in," Markin said.

"He described in detail the circumstances of the way he, Left Front coordinator Sergei Udaltsov and other persons had planned to organize massive unrest in the territory of the Russian Federation and also the involvement of the said persons in massive unrest that occurred in Bolotnaya Square on May 6," Markin said.

"It follows from Razvozzhayev's confession that this unrest was financed by Targamadze," Markin said.

Markin recalled that Razvozzhayev was put on the federal wanted persons list on October 18.

Razvozzhayev has been arrested by court at the request of the Main Investigations Department of the Investigations Committee in connection with the criminal case opened on the basis of the preparations for the organization of mass riots in Moscow and other regions of Russia following a probe into the facts stated in the film Anatomy of Protest-2.
