• the Investigative Committee of the Russian Federation has
already opened two criminal cases 
... one for "violation of the rules of safety preparedness" («Нарушение правил полетов и подготовки к ним») and another for "provision of unsafe services" («Оказание небезопасных услуг»). Quick work, comrades!
The usual practice in Russia. Just as raiding the offices. So don't think too deep into it. The next news will probably be that some embezzlement was discovered. Which also shouldn't surprise anyone because embezzlement is also a standard practice in Russia.
