A member of Russian punk protest band Pussy Riot is gravely ill in hospital after a possible poisoning, according to Russian news reports.
Ekho Moskvy radio and online news portal Meduza reported on Wednesday that group member Pyotr Verzilov has been in emergency care since late Tuesday.
They quoted fellow Pussy Riot member, Veronika Nikulshina, as saying Verzilov's symptoms included losing eyesight and ability to speak.
Nikulshina said Verzilov was being treated in the toxicology unit at Moscow hospital, indicating suspected poisoning.
A post on the band's official Twitter account said: "His life is in danger. We think that he was poisoned."
Verzilov, Nikulshina and two other activists served 15-day jail sentences for disrupting July's World Cup final.
They ran onto the field wearing police uniforms, briefly interrupting the match between France and Croatia.
Pussy Riot said they were protesting excessive police powers in Russia.
