Malaysia's embattled Prime Minister Najib Razak denied accusations of misuse of power, graft and interference in official investigations of troubled state fund 1MDB, according to documents filed in response to a lawsuit, Bloomberg reported on Tuesday.
In the suit, Mahathir, who has repeatedly said he wants Najib removed from office, alleges Najib "actively and deliberately" tried to derail investigations into 1Malaysia Development Bhd. and into allegations that funds from 1MDB ended up in his personal accounts, the report said.
The prime minister's office did not immediately answer two emails from CNBC, sent several hours apart, nor did it answer several phone calls. Representatives of Mahathir didn't immediately return emails from CNBC requesting comment.
Questions about movement of funds from 1MDB came to widespread attention nearly a year ago, when the Wall Street Journal reported that in 2013 nearly $700 million had flowed from the debt-ridden fund to Najib's personal bank account.
Najib has repeatedly denied wrongdoing and, under pressure from the outcry caused by the WSJ report, said the funds were a private donation from a Middle Eastern country he declined to name. He has denied benefiting personally from the funds.
The MAS said the Switzerland-based bank had lost its status as a merchant bank in Singapore due to "serious breaches of anti-money laundering requirements, poor management oversight of the bank's operations, and gross misconduct by some of the bank's staff." It was the first time since 1984 that MAS had withdrawn a merchant bank's approval.
In a related development, Abu Dhabi wealth fund International Petroleum Investment Company (IPIC) said in a London Stock Exchange filing on Tuesday that it would seek arbitration in London courts over what it called 1MDB's failure to make contractual payments. The Abu Dhabi fund claimed it was seeking around $6.5 billion from 1MDB.
Last year, a 1MDB unit transferred funds owed to IPIC to a British Virgin Islands entity called "Aabar Investments PJS Ltd.," which has a name closely resembling Aabar Investments PJS, an IPIC subsidiary, according to a Wall Street Journal report.
According to a Wall Street Journal report Tuesday citing people familiar with the matter, 1MDB was provided with documentation showing the British Virgin Islands company to which it sent more than $3.5 billion was owned by IPIC's Aabar Investments PJS.
