“The court granted the petition of the investigation and chose a preventive measure for Kuzmin in the form of detention until December 24,” TASS quotes the judge’s decision.

Earlier it was reported that the head of Rostec, Sergei Chemezov, was declared a victim in an extortion case against the commercial director of journalist Ksenia Sobchak, Kirill Sukhanov, and the former editor-in-chief of Tatler magazine, Arian Romanovsky.

A court in Moscow arrested Sukhanov, he declared his readiness to partially admit his guilt and apologize to Chemezov.

Sukhanov's defense is appealing against his arrest.

On October 26, a source told RT that Sobchak had left Russia prior to the searches of her Moscow suburban home and the arrest of her commercial director, Kirill Sukhanov, in an extortion case.

According to the interlocutor, Sobchak herself also became a defendant in this case and could have been detained if she had not left Russia.
