Wanted 1MDB-linked businessperson Jho Low is in Macau, said inspector-general of police Mohamad Fuzi Harun.
Fuzi said Malaysian police had searched for him in Hong Kong, but that he had left the special administrative region when they arrived.
"The latest we know he was in Macau. In fact the other day we sent our team to Hong Kong, but immediately when we arrived, he left to Macau," Fuzi said when met by reporters in Putrajaya today.
The special administrative region of Macau does not have any extradition treaties with other countries.
Fuzi was met after attending the Home Ministry's Hari Raya Aidilfitri open house.
Low is a key figure in the 1MDB scandal.
The US Department of Justice (DOJ) claimed in its suits that the businessperson was involved in multiple instances where 1MDB funds were allegedly misappropriated.
He is accused of having used 1MDB funds to purchase superyacht the Equanimity; jewellery for model Miranda Kerr; and also a US$27.3 million pink diamond necklace for the wife of Malaysian Official 1 (MO1).
The DOJ claimed the pink diamond was purchased using the US$620 million that MO1 claimed to have returned to a royal Arab donor, but was instead channelled to accounts allegedly controlled by Low.
MO1 has been identified as Najib Abdul Razak, the former prime minister.
