Auditor-general Ambrin Buang believes the audit report he submitted to the Public Accounts Committee (PAC) on 1MDB is sufficient to initiate further investigations.

"I think our report is sufficient as a basis for further investigation, we have done our job.

"The next step, as recommended by PAC, they (the committee) want investigation on certain personalities in the company.

"Let the police do their work, we will assist anyone who wants (to) investigate," he told Channel News Asia (CNA) in an interview.

However, Ambrin declined to comment on whether he thought the audit findings revealed elements of wrongdoing.

"My view is not important, I cannot comment on anything that's criminal as criminality must be investigated according to criminal law and procedures," he said.

The auditor-general told CNA that it is up to the attorney-generals of Malaysia and other countries investigating 1MDB to decide whether there is a prima facie case .

The National Audit Department was instructed to look into 1MDB after reports emerged of questionable monetary transfers and investments linked to the fund, along with its extremely high debt exposure.

The PAC which incorporated the AG's report on 1MDB into its findings tabled in Parliament last month, had recommended that former CEO Shahrol Halmi and his management team be investigated for weaknesses and irregularities identified in the fund.

The 1MDB board of directors were also singled out for failing to keep a firm hold on the management.

The board has offered to resign and their resignation was accepted by the Finance Ministry, while Shahrol is under investigation but has yet to be questioned by the police.
