MOSCOW, July 20 (RAPSI, Lyudmila Klenko) – A probe into the criminal case against Russian investigators casts a shadow on the whole Investigative Committee of Russia, but further work on self-purification of the structure will continue, official representative of the Committee Vladimir Markin said.

Earlier, deputy head of the Investigative Committee’s Moscow Directorate, Denis Nikandrov, and several of his high-ranking colleagues have been arrested by the Federal Security Service (FSB) on suspicion of receiving a large-scale bribe.

Later suspects were detained by the Lefortovsky District Court of Moscow.

According to the official website of the FSB, the agency, along with the Investigative Committee, is carrying out a probe into the criminal case against the suspects over alleged abuse of office and receiving bribes from some representatives of the criminal community.

On Tuesday, various media outlets reported that Nikandrov and his colleagues were arrested by the FSB as a part of the investigation into the criminal case over extortion of 8 million rubles ($127,000) that involved gang leader Zakhariy Kalashov also known in the criminal world as Shakro Molodoi.
