'Torture chamber' found in Moscow

Moscow police investigating an alleged abduction have found what appears to be a torture chamber in a basement in an upmarket area of the Russian capital.

A cage and electric shock devices were found in the basement of a large house, Russia's Kommersant newspaper reported.

Police were led to the basement by a man who says he was tortured there.

The man, from southern Russia, was found in the street handcuffed and wearing only his underwear after he managed to escape, media reports say.

Magomed Khamkhoyev, a 35-year-old Ingush man, told police he had been kidnapped and tortured in the basement of the cottage in Serebryanny Bor, according to Kommersant.

He said his captors had shown him a corpse and threatened him with a similar fate.

A criminal investigation has been opened into Mr Khamkhoyev's abduction, Russian officials said in a statement.

Community leaders from Ingushetia, a troubled Russian republic in the North Caucasus, say up to 10 Ingush have gone missing in the capital this month.

Some media reports suggest Mr Khamkhoyev's kidnapping could have been linked to investigations into the disappearances.

Some of the abductions are believed to have been carried out as a revenge for the Beslan school seizure in North Ossetia in 2004, in which more than 330 people died, many of them children.

Some of the pro-Chechen attackers were ethnic Ingush.
