MOSCOW, October 5 - RAPSI. The Interior Ministry's investigator was arrested on suspicion of receiving a $3 million bribe, a source in the law enforcement authorities told RIA Novosti on Wednesday.

Major Nelli Dmitriyeva was a chief investigator of the Moscow police's investigative department. She was mostly dealing with economical and financial crimes. Dmitriyeva has been working as an investigator for more than 11 years. Before that she used to work as the economist for 14 years.

Media sources earlier reported that Dmitriyeva was involved in the notorious case of Hermitage Capital Management lawyer Sergei Magnitsky, who was accused of corporate tax evasion and who died in a pre-trial detention center in November 2009.

His death evoked a major public outcry.

The law enforcement authorities have not given any comments to RIA Novosti thus far.
