In a statement today, MACC said the assets, whether within or outside the country, must be declared within 30 days from the date of the notice.
The commission said the notice was served after the son of the former prime minister Tun Dr Mahathir Mohamad presented himself at the MACC headquarters at about 9.30 am yesterday to assist in its ongoing investigation.
"The notice is a follow-up action from the MACC's investigation into the information from the Panama Papers, as well as his business activities involving the sale and purchase of government-linked companies (GLCs)," it said.
The investigation is being conducted under the MACC Act 2009 as well as the Anti-Money Laundering, Anti-Terrorism Financing, and Proceeds of Unlawful Activities Act 2001 (AMLATFPUAA).
The MACC initiated the investigation in August 2022 as part of its investigation into all entities mentioned in the Pandora Papers and Panama Papers reports.
To date, the MACC said it has called 10 witnesses for statement recording purposes.
"The MACC is examining financial documents and asset ownership of the entities listed in those reports, and the investigation is still actively ongoing," it said.
