The 67-year-old was found guilty of seven charges related to criminal breach of trust (CBT), money laundering and abuse of power, and he was sentenced to 12 years in prison and a RM210 million fine.
With Najib now being under the hot seat, the attention has also shifted to another Malaysian who is said to be the mastermind of the whole 1MDB-SRC International scandal: fugitive businessman Jho Low.
The 38-year-old has been on the run since the 1MDB case made international headlines in 2015, and despite all the satellite technology we have, no one is able to pinpoint where he is.
And now, even the country that many are claiming Low to be sheltering in has denied his existence.
Where is he then?
Reuters reported that China has denied protecting the businessman, adding that they do not know where he is.
Earlier this week, Malaysia’s national police chief Tan Sri Abdul Hamid Bador was quoted by Malay daily Utusan Malaysia as saying that Low was hiding in Macau.
When attempts were made to extradite him, Chinese authorities reportedly “appeared insincere” in their efforts to cooperate, Abdul Hamid said.
China has since rubbished the claims, saying that their police had investigated all possible leads, but they were still unable to trace him.
"The position of the Chinese government on combating crime is consistent and clear-cut.
"China does not and will never shelter foreign criminals," the Chinese embassy in Kuala Lumpur said in a statement quoted by the news agency.
China has assured its Malaysian counterparts that they will continue to give assistance and support to their investigations.
According to the report, Low's spokesperson previously said that the financier has been offered asylum in an unidentified country.
Low has been charged in Malaysia and the United States over allegations that he masterminded the theft of USD4.5 billion (RM19.1 billion) from 1MDB, which was co-founded by Najib.
Maybe it's true; maybe Jho Low really turned into a bear:
