In the most prominent money-laundering case, Raul Arashukov, an adviser to the head of a Gazprom subsidiary, was detained on an allegation of stealing Rbs30bn ($460m) worth of gas. His son Rauf Arashukov was also detained. Father and son deny the allegations and remain in detention. While this money-laundering case is unlikely to have led to Monday’s top executive departures, it adds to the unsettled atmosphere at the gas producer. “We are talking about full-scale changes,” a London-based analyst said of the executive departures. “It is unlikely they were linked to the Arashukovs’ case. “But perhaps this case simply exhausted the patience at the top regarding the company’s management.” Kurt Bilgaard Pedersen,
