A Swiss businessman who allegedly leaked thousands of emails to the Sarawak Report has been arrested in Thailand at the behest of a controversial oil exploration company connected to the1MDB scandal in Malaysia. The Swiss national, Xavier Justo, has been held in Thailand for the past two days on charges of blackmail and extortion at the request of PetroSaudi International, which claims that Justo, a former PetroSaudi director, stole the emails and passed them to Clare Rewcastle Brown, the British blogger who operates the Sarawak Report and who has mounted a no-holds-barred campaign to expose alleged wrongdoing at 1MDB.
