Moscow (CNN) A member of Russian protest group Pussy Riot has arrived in Berlin for medical treatment, following what the activists claim was a suspected poisoning in Moscow last week. Pyotr Verzilov, who is also the husband of prominent band member Nadezhda Tolokonnikova, flew into Berlin on Saturday, according to Germany's Cinema for Peace Foundation, a non-profit humanitarian group that has previously advocated for Pussy Riot and which organized the flight. The activist's wife, better known as Nadya, on Saturday posted a photo on Twitter of her visitor badge at Berlin Brandenburg Airport, saying he would soon be arriving. The Russian punk band -- known for obscuring their identities with colorful balaclava-style masks -- is an outspoken critic of the Putin government. Russian foreign ministry spokeswoman Maria Zakharova had no comment on Verzilov's illness, when contacted by CNN.
