Eight members of an all-girl punk group called Pussy Riot wearing brightly coloured mini-dresses and balaclavas climbed over railings onto a stone platform next to the cathedral to sing a song called Putin Has P***** Himself.
Russian police stood by while the band performed the song before detaining all the members and taking them to the nearby Kitai-Gorod police station.
Four members were later charged with the non-criminal public order offences and disobeying police, carrying a maximum punishment of 15 days behind bars, according to one band member who uses the nickname Garadzha Matveyeva.
In December the band gave a roof-top concert next to the police cell where protest leader and blogger Alexei Navalny was serving a short sentence.
They have also performed in the Moscow metro.http://www.telegraph.co.uk/news/worldnews/europe/russia/9028106/Russian-all-girl-punk-band-Pussy-Riot-arrested-for-performing-Vladimir-Putin-song.html
