Former senator Ezam Mohd Nor has urged the Malaysian Anti-Corruption Commission (MACC) to reopen its probe on 1MDB’s former subsidiary SRC International Sdn Bhd.

Ezam said he lodged the report at MACC Selangor headquarters in Shah Alam this morning, following questions and warnings raised by former second finance minister Ahmad Husni Hanadzlah during his Budget 2017 debate on Monday.

He also said the report was lodged to protect the interests of some 1.6 million contributors to Malaysia’s Retirement Fund Incorporated (KWAP), the country’s civil service pension fund.

“Taking into consideration the extraordinary RM4 billion loan to SRC, MACC should also investigate all of KWAP’s board members and top management,” he said in a statement.

He said this in reference to Husni’s statement that the RM4 billion loan from KWAP was disbursed all at once, instead of in staggered amounts as per standard procedure.

KWAP’s chief executive officer had previously said SRC International has so far yet to incur any arrears on its loan.

However, Ezam said there are still concerns over the remaining amount owed, until the year 2022.

“According to Singapore’s The Straits Times report in July, the value of SRC’s investments had dropped significantly and a China firm was in the process of handing it a lifeline.

“If this report is true, the risk of SRC failing to pay back its loan to KWAP in the future would be greater,” he cautioned.

The Swiss Attorney-General’s Office (OAG) earlier this month said its investigations revealed substantial amounts of money were allegedly misappropriated from SRC International and that fraud was committed based on a “Ponzi scheme-like" operation to cover it up.

The MACC earlier probed how RM42 million from SRC International went to Prime Minister Najib Abdul Razak.

The PM was in January exonerated by attorney-general Mohamed Apandi Ali, who said Najib was not aware that the funds were transferred to him.

Whistleblower website Sarawak Report this month alleged that bank records show former SRC International managing director Nik Faisal Ariff Kamil managing bank accounts purportedly belonging to Najib.

The website claims large cash deposits were made to the accounts in February and March 2015.

The PM did not respond to requests for comment on the latest allegations.
