KUALA LUMPUR, July 25 — Malaysia’s enforcement agencies must take immediate action if the US Department of Justice succeeds to prove in court the allegations of financial misappropriation from state-owned 1 Malaysia Development Bhd (1MDB), Umno Youth chief Khairy Jamaluddin said today.

In the meantime, he advised Malaysians to let the due processes take place and refrain from speculating on the affair.

"We take cognisance that this case has yet to be proven and that it should be taken to court. The civil case will determine if the assets are procured illegally [as claimed] and we hope the process will be allowed to take place.

"We do not want any parties to presume anyone as guilty yet because [the suit] was only an investigation, so we let the court process to take place,” Khairy told reporters after chairing the wing’s executive councillor meeting here.

"Although we do not want to pre-empt or make any assumptions, it is important for local enforcement agencies to launch an investigation should it be true that there was embezzlement,” he added.

He also supported the call by Prime Minister Datuk Seri Najib Razak for those named in the US Department of Justice’s (DOJ) civil suit to step forward and clear their names to show that there was no misuse of public funds as alleged.

Earlier today, Najib said the government took a serious view of the US DOJ report and was prepared to extend full cooperation to all involved in the investigation.

"We agree with the PM that those identified in the suit must be responsible to defend themselves… so that there are no more speculation,” he said.

But Khairy denied that the person referred to in the US lawsuit as "Malaysian Official 1” needed to clarify.

"No, those who are named as the owners of the assets for forfeitures,” he said.

He also said he would not speculate on the identity of "Malaysian Official 1”.

The US DOJ recently filed civil lawsuits to seize assets acquired with money allegedly misappropriated from 1MDB, the government investment fund.
