Pussy Riot

The group gained global notoriety when five members of the group staged a performance inside Moscow's Cathedral of Christ the Saviour in February 2012, an action condemned as sacrilegious by the Russian Orthodox Church. Three members of the group were arrested, tried, convicted, later amnestied and released on probation. The trial and sentence attracted considerable attention and criticism, particularly in the West. The case was taken up by human rights groups, including Amnesty International, which designated the women as prisoners of conscience, and by a number of prominent entertainers. Public opinion in Russia was generally less sympathetic towards the band members.
In February 2014, a statement was made anonymously on behalf of some Pussy Riot members that Alyokhina and Tolokonnikova were no longer members. However, both were among the group that performed as Pussy Riot during the Winter Olympics in Sochi, where group members were attacked with whips and pepper spray by the Russian Cossack paramilitary employed as security guards.
