Malaysia's new administration came to power earlier this month in a shock victory and quickly reopened investigations into the fund, whose full name is 1Malaysia Development Bhd.

Shukri was addressing a news conference after Najib arrived at the headquarters of the Malaysian Anti-Corruption Commission (MACC), which has ordered him to explain a suspicious transfer of $10.6 million into his bank account.
Najib had said little since the raids other than to complain to local media about how they were conducted.
Datin Seri Rosmah Mansor, wife of former Prime Minister Datuk Seri Najib Razak, hopes that the authorities will respect the process of law in the course of their investigation to avoid any premature judgment by the public.

A government official has said Najib could possibly be detained after giving his statement to Malaysia's Anti-Corruption Commission.

SRC was created in 2011 by Najib's government to pursue overseas investments in energy resources, and was a unit of 1MDB until it was moved to the finance ministry in 2012.
The new 1MDB task force will liaise with enforcement agencies in the United States, Switzerland, Singapore, Canada and other related countries.
The U.S. Justice Department said in a statement that it looks forward to working with Malaysian law enforcement in investigating the 1MDB case.
