Swiss prosecutors said on Tuesday they were investigating two officials from Saudi energy group PetroSaudi International as part of a wider inquiry into the suspected theft of assets from Malaysia’s 1MDB state fund. A Malaysian board game based on “Monopoly” is taking aim at the massive 1MDB scandal before elections, featuring a motley crew of figures central to the controversy and items allegedly bought with looted money. Prime Minister Najib Razak has insisted there was no wrongdoing in the 1MDB scandal and instead blamed a “problematic business model” for the billions of dollars that went missing from a government investment fund.
