Incarcerated Pussy Riot member Nadezhda Tolokonnikova has been moved to a prison hospital following health complaints.

The 22 year old has been removed from the remote IK-14 women’s penal colony, where she has been resident since October of last year. In a statement, her lawyer Irina Khrunova said that Tolokonnikova was moved on January 24 following an official appeal by the prison director. Following a special examination, doctors concluded that the cause of her headaches could be “very serious”. Tolokonnikova has complained of headaches since her trial, when she was convicted on hooliganism charges relating to the group’s “punk prayer” at Moscow’s Cathedral of Christ the Saviour in February 2012.

As The Guardian explain, conditions in IK-14 are largely indistinguishable from those in the original Russian gulags. Female inmates are required to sleep in large barracks with up to 200 other women, are forced to perform extensive daily labour, and must always wear full prison uniform. Tolokonnikova is apparently exhausted after being forced to sew security service uniforms eight hours a day, as well as performing additional evening duties.

Two weeks ago, fellow Pussy Riot member Maria Alekhina was denied a deferral of her sentence on the grounds that she needed to care for her young son. Ekaterina Samutsevich, the third of the original defendants, was freed on appeal last October. A documentary about the protest group’s predicament, Pussy Riot – A Punk Prayer, premiered at the Sundance Film Festival last week.
