U.S. investigators have accelerated their probe into the 1MDB sovereign wealth fund set up by former Malaysian Prime Minister Najib Razak and are exchanging more evidence with Malaysian authorities since Najib lost last month's election, three sources with direct knowledge of the probe said.
At least six countries, including Malaysia, the United States and Switzerland, are investigating accusations that Najib and associates pocketed part of $4.5 billion allegedly stolen from the state-run investment fund, 1Malaysia Development Berhad.
The probe received a boost after Najib unexpectedly lost the election on May 9.
