MOSCOW, December 3 (RAPSI) - The alleged leader of a notorious organized-crime syndicate Aslan Gagiyev, who was extradited from Vienne to Russia in June, pleaded not guilty to multiple murders, the Investigative Committee’s press service reports Monday.

He also denied involvement in the organization of a criminal group and robberies with violence and withheld evidence, according to investigators. 

Investigation into the case against Gagiyev is completed, the statement reads.

Russian investigators claim that Gagiyev’s gang has been operating since 2004 and includes over 50 members. Members of the gang committed more than 60 counts of murder in Moscow, Moscow Region and North Ossetia including murders of officials, law enforcement officers and businessmen.

Over 20 members of the gang have been already given long prison terms, two persons have been sentenced to life, and one individual have been sent to compulsory treatment.
