The Malaysian Anti-Corruption Commission said its investigations found that 2.6 billion ringgit ($675 million) in Prime Minister Najib Razak's personal accounts are donations and not from a debt-ridden state investment company.

The agency has completed its probe of the premier's accounts and sent the results to the attorney general, it said in an emailed statement Monday. The probe was done in a free, transparent and professional manner, it said, without indicating where the donations came from or why millions of dollars in such funds would be deposited in Najib's personal bank accounts.

The Wall Street Journal reported July 3 that $700 million may have moved through government agencies and state-linked firms to accounts bearing Najib's name. The premier has denied taking money for personal gain and has described the furor as part of a campaign to remove him from office.
