The stepson of Malaysian ex-Prime Minister Najib Razak pleaded not guilty Friday to laundering $248 million from the 1MDB state investment fund, becoming the third person in his family to face charges in the scandal.

Hollywood producer Riza Aziz was freed on bail a day after being detained by anti-graft officials. He was solemn as he appeared in court to be charged with receiving the illicit funds between 2011 and 2012 in the U.S. and Singapore. The charge sheets said the money was misappropriated from 1MDB and channeled into bank accounts of his Hollywood company Red Granite Pictures Inc., which produced films including the Martin Scorsese-directed “The Wolf of Wall Street.”

Riza, 42, was charged with five counts of money laundering, and he could face up to five years in prison, a fine or both, on each count if he is convicted.

Najib set up the 1MDB fund to finance development in Malaysia, but it accumulated billions in debts and U.S. investigators allege at least $4.5 billion was stolen from the fund and laundered by Najib’s associates.

Public anger over the alleged corruption contributed to the shocking election defeat of Najib’s long-ruling coalition last year, and the new government reopened investigations that had been stifled while Najib was in office.

Najib is on trial for alleged criminal breach of trust, abuse of power and money laundering linked to 1MDB. He denies the charges. His wife and Riza’s mother, Rosmah Mansor, also has pleaded not guilty to money laundering and tax evasion related to 1MDB but her trial date has not been set.
