The Commercial Court of Moscow has arrested Bashneft’s stocks owned by Russia’s largest publicly traded holding Sistema.

      The prosecutors insist the privatization deal was fraught with violations and that the stocks must be returned to the state.

      Sistema purchased Bashneft from the son of Bashkortostan’s former leader. According to the police, that son privatized the assets illegally and laundered the funds by selling this major oil company to Yevtushenkov’s Sistema at what they claim was a lower price.

      According to the corporate press release, “Sistema's management believes that the acquisition of BashTEK group was legal and transparent. The company is fully cooperating with the investigation and intends to use all legal means to defend its position.”

      Rumours around the detention include Rosneft’s push to buy Bashneft at a cheap price to ramp up its production capabilities amid sanctions limiting Igor Sechin’s plans to develop offshore fields.

      Rosneft has strongly rejected the allegations but it is still very much in the news, with many comparing Yevtushenkov to another oligarch, Mikhail Khodorkovsky.
