MOSCOW, July 28 (RAPSI) - Moscow’s Presnensky District Court has placed businessman Nikolai Martynov, who stands charged with embezzling 3 billion rubles ($51million) allocated for the purchase of electronic monitoring bracelets for Russia’s Federal Penitentiary Service (FSIN), under house arrest, RAPSI learnt in the court on Tuesday.

The defendants in the case are also former head of FSIN Alexander Reimer, his former deputy Nikolai Krivolapov, director of FSIN’s Information and Technical Support Center Viktor Opredelyonov.

Investigators claim that Reimer and Krivolapov personally approved the purchase of the electronic bracelets at vastly inflated prices.

The probe into the case was opened after two FSIN employees were detained on suspicion of extorting $2.6 million from a businessman in connection with the purchase of the bracelets.

Reimer, Martynov and Opredelyonov were put in jail. Krivolapov was placed under house arrest.

Reimer’s assets worth 15 million rubles have been seized. 

Investigative Committee spokesman Vladimir Markin earlier said investigators are working to establish other possible suspects in this crime.
