Malaysia’s ousted Prime Minister Najib Razak on Monday said he did not benefit or steal money from 1Malaysia Development Berhad (1MDB), as authorities searched a new premise and sought additional witnesses in an ongoing probe on the state fund. Malaysia is investigating allegations that billions of dollars had been siphoned from 1MDB, which Najib founded and was a key reason behind his shock loss in an election last month. 1MDB was founded by Najib in 2009 and is the subject of money-laundering probes in at least six countries, including the United States, Switzerland and Singapore. The US Department of Justice has alleged that more than US$4.5 billion was misappropriated from 1MDB, and about US$700 million of that went to Najib’s personal bank accounts.
