Sochi Six group members - five women and one man - donned their signature ski
masks and were pulling out a guitar and microphone as at least 10
Cossacks and other security officials moved in. One Cossack appeared to
use pepper spray, another whipped several group members while others
ripped off their masks and threw the guitar in a rubbish bin.
Police arrived and questioned witnesses, but no-one was arrested.
The
Cossacks violently pulled masks from women's heads, beating group
member Nadezhda Tolokonnikova with a whip as she lay on the ground.
