(FILES) A file picture taken on July 20, 2012 shows members of the all-girl punk band «Pussy Riot» Nadezhda Tolokonnikova (C), Maria Alyokhina (R) and Yekaterina Samutsevich (L), sitting behind bars during a court hearing in Moscow. Prosecutors asked a Moscow court to lock up members of the Pussy Riot girl band for three years after they called for Vladimir Putin’s ouster in a song, prompting Madonna to plead for clemency. As the full hearings in the controversial trial went into a second week, the state prosecutor said the young women’s crime was so severe they needed to be isolated from society.
