MOSCOW, January 31 (RAPSI, Lyudmila Klenko, Yevgeniya Sokolova) - Investigators have filed a motion demanding to extend until April 6 the detention of Vlad Novikov, a former officer of the Russian Federal Security Service (FSB), and Karen Krayukhin, an officer still in FSB service, who stand charged with bribery, attorney Dagir Khasavov told RAPSI on Tuesday.

The motion will be considered by the Moscow Garrison Military Court on February 3.

As it has been reported, Novikov and Krayukhin have been arrested on suspicion of taking a bribe from the Turkish construction firm Esta Construction.

Investigators claim that Esta Construction has been fined over 37 million rubles ($570,000) for violation of migration legislation. The company’s lawyer in order to avoid payment of the fine asked the defendants for help in the termination of the case for 5 million rubles ($77,000).

In September, a military prosecutor told RAPSI that criminal proceedings may be instituted against Esta Construction lawyer Valerian Kochergin, who has been initially recognized as victim in the case.

Esta Construction is a contracting company established by Bahattin Demirbilek in Moscow in 2006 and operating as a general contractor and project designer in international construction market, the firm’s website says.
