The wife of jailed Russian activist Ildar Dadin, who has claimed he was tortured and beaten in prison, says her husband has been confined to his cell.
Anastasia Zotova wrote on Facebook on December 1 that the ombudsman in Karelia, where her husband is serving his 2 1/2-year prison term, visited Dadin.
The ombudsman found out that Dadin had been transferred to a so-called closed-regime premises (PKT) in the penal colony for a period of six months for a "brawl with other inmates," Zotova said.
PKT is a jail inside a penal colony where inmates are kept in their cells all the time.
Dadin, 34, was the first person convicted under a Russian law criminalizing participation in more than one unsanctioned protest.
In November, he claimed he and other prisoners had been beaten and tortured in prison.
Officials in Russia's Federal Penitentiary Service say they have found no evidence to support Dadin's allegations.
