The Malaysian Anti-Corruption Commission (MACC) has vowed to complete its investigation even in the absence of Abdul Gani Patail as attorney-general.

"In the case of (former 1MDB subsidiary) SRC International Sdn Bhd, with or without the special task force (probing 1MDB), with the absence of Abdul Gani, MACC assures the investigation on SRC International will continue until completion," said the commission.

Upon completion of the investigation, MACC said it would submit its findings to the deputy public prosecutor for perusal and further action.

In its statement today, MACC reiterated it is only investigating SRC International and not 1MDB.

"This was the decision made by the special task force comprising the police, Bank Negara and MACC which obtained guidance and legal advice from Abdul Gani who was then attorney-general," added the commission.

MACC said it is in the process of tracing several key witnesses in order to complete the investigation on SRC International.

"MACC calls on the people to give it the space to complete its investigation," added the commission.

The special task force was formed to look into allegations concerning 1MDB, including the claim that RM2.6 billion was deposited into Prime Minister Najib Abdul Razak's personal bank accounts in AmBank.

According to a report in The Wall Street Journal on July 3, a total of US$681,999,976 (RM2.6 billion) was allegedly wire transferred by an Abu Dhabi fund Aabar into Najib's private AmBank account in Kuala Lumpur on March 2013, two months before the May 5, 2013 general election.

Following this, another RM42 million was purportedly transferred from SRC International into Najib's three private accounts at AmPrivate Banking as recent as five months ago.

SRC International Sdn Bhd is a company linked to 1MDB, which is now under the Finance Ministry.

According to reports, SRC International had transferred RM10 million on Feb 10, 2015, into the account number of ‘Dato’ Sri Mohd Najib Bin Hj Abd Razak’ at AmPrivate Bank for a corporate social responsibility (CSR) programme.

There were allegedly two earlier transfers of RM27 million and RM5 million on Dec 26, 2014.

Responding to the WSJ report, which cited information from Malaysian investigators, the prime minister has denied using public funds for his personal gain.
