The head of a pro-Putin youth group says an effort to identify secret members of the Russian punk rock group Pussy Riot is succeeding. On his website, Konstantin Goloskokov, the head of Nashi, said a number of people have responded to an offer to pay cash for information, RIA Novosti reported. Goloskokov said some of those identified as Pussy Riot members had already been publicly identified with the group by participating in demonstrations and giving interviews. Goloskokov said all his information is being shared with police. Three members of Pussy Riot have been sentenced to two years each in prison for a protest against Russian President Vladimir Putin at the Russian Orthodox cathedral in Moscow.
