So much money was pouring so rapidly into the Malaysian Prime Minister's personal bank accounts that it rang internal money-laundering alarms inside AmBank. Hundreds of millions of dollars were being wired into Najib Razak's accounts from the Saudi Arabian Government, a mysterious Saudi prince and two shadowy British Virgin Island companies, while the head of a Malaysian state-owned company topped up the Prime Minister's credit card accounts with millions of Malaysian ringgit in cash. Inside the bank, the Malaysian Prime Minister's account was held under the codename "Mr X". The startling new banking records have been obtained as part of a Four Corners program that aired last night, and which resulted in the arrest of two members of its team.
