Jailed Pussy Riot member Nadezhda Tolokonnikova, who went missing for two weeks, is heading to a new penal colony in Siberia, according to her husband.

Pyotr Verzilov said on Twitter that he is 100% sure Tolokonnikova was being transferred to a prison in Krasnoyarsk region, about 2,000 miles from Moscow.

A reliable source told him that the Pussy Riot feminist will settle in the penal colony number 50 in the town of Nizhny Ingash, four time zones away from Moscow and on the Russia's Trans-Siberian railway.

The reason behind the move, according to Verzilov, is punishment for Tolokonnikova's public statement in which she denounced the conditions in her women's prison camp, located in the region of Mordovia.

The Pussy Riot member went on hunger strike in protest against "slave labour" conditions and harassment by colony administration. She wrote an open letter describing the forced-labour routine, reminiscent of Soviet-era Gulags - triggering a huge debate in Russia and worldwide.

However, the 23-year-old activist was later put on "information blockade" and on 21 October prison service said she was being moved from the Mordovia prison.

Her husband said he lost sight of Tolokonnikova from 22 October.

Russian human rights commissioner Vladimir Lukin told Interfax that the jailed Pussy Riot member was feeling well and eating properly.

"Acting at the request of several human rights campaigners, I got in touch with the administration of the Federal Penitentiary Institutions Service and asked them about convict Tolokonnikova. I was told that she is fine and she is still on her way to one of the penitentiaries where she will continue to serve her sentence," Lukin said.

"Tolokonnikova is traveling in a separate compartment for security reasons. She is held in a separate cell during stopovers," he said.

"She is being accompanied by a doctor. She is eating properly and is said to be in satisfactory condition," he said.

Tolokonnikova is just months away from the expiring date of her two-year prison term for the "punk prayer", performed in Russia's main Orthodox cathedral in Moscow.
