A prominent member of Russian punk band Pussy Riot has regained consciousness following a suspected poisoning, according to a person close to him.

Petr Verzilov, one of several Pussy Riot members who protested at the World Cup final in Moscow in July, is no longer in the intensive care unit at the hospital in Moscow, fellow band member Veronika Nikulshina told the Russian online news portal rtvi.com on Friday.

The government critic was brought to the hospital on Tuesday with impairments to his sight, speech and consciousness.

It is believed that he ingested a powerful medication that suppresses the neurotransmitter acetylcholine. According to media reports, doctors found evidence of strong psychotropic drugs in his blood tests.

Verzilov was one of four Pussy Riot protesters who, dressed in police-style outfits, stormed the pitch during the World Cup final between France and Croatia.

The protesters served 15 days in jail for the incident, which the band said they conducted to demand greater political choice in Russia and the release of political prisoners.
