The producer of the Leonardo DiCaprio film The Wolf of Wall Street has been arrested on money laundering charges in Malaysia.
Riza Aziz is the stepson of former prime minister Najib Razak.
Mr Razak is accused of misappropriating $970 million from a multi-billion-dollar state fund, the 1Malaysia Development Berhad (1MDB). His wife Rosmah Mansor is also charged with money laundering and tax evasion. Both have pleaded not guilty.
Mr Aziz denies the charges and will appear before a Malaysian court today.
His production company, Red Granite, has previously settled a civil lawsuit with the US Government, where it accused him of using money from the fund to finance the movies Dumb and Dumber To and Daddy's Home.
The production company agreed to pay $76 million to settle the claims but denies any wrongdoing.
DiCaprio was also a producer on the 2013 film and won a Golden Globe award for best actor for his performance. He thanked Mr Aziz in his acceptance speech.
The 1MDB fund was founded by Mr Najib in 2009 as a vehicle to create long-term economic development in Malaysia.
Less than a decade on, it was being investigated in at least six countries for alleged money laundering and graft.
Civil lawsuits filed by the US Department of Justice allege that nearly $US4.5 billion ($6.3 billion) was misappropriated from 1MDB during its lifespan.
The scandal helped to bring down Mr Najib's government, with Malaysian voters ousting him amid a tide of public disgust in May last year — the first time his party had lost power since the country gained independence from Britain in 1957.
