The 12th defendant in the Crocus City Hall terrorist attack case, Dzhumokhon Kurbonov, was arrested by the Basmanny District Court of Moscow and will stay in custody until May 22, a Sputnik correspondent said on Saturday. 

The investigators requested the court to arrest him earlier today. 

The Moscow City Court said that Kurbonov allegedly provided a means of communication to his accomplices and gave them money to pay bills. 

The defendant's lawyer said that Kurbonov himself agreed to his arrest. 

West covering up real culprits behind Crocus attack: Russia

The Russian Foreign Ministry claimed on April 8 that Western media has been instructed to conceal the truth about the terrorist attack on the Crocus City Hall concert in Moscow as a means to dilute sympathy with the Russian people. 

The ministry also added that media manipulation serves to "distract" the world from the real perpetrators of the attack. 

In its statement, the Foreign Ministry dubbed the move as "cynical due to categorical instructions not to publish the true scale of the tragedy in the media, not to mention the number of victims of the terrorist attack, the dead children, and not to demonstrate the reaction of ordinary citizens to the incident." 

It added that special instructions had been given that spread a distorted narrative of the attack that implicated ISIS. 

Russia believes that it is "extremely hard to believe" that ISIS is behind the wide and fatal attack on the Moscow concert hall, as Russian intelligence and security officials believe Ukraine and allied Western backers are behind it.
