NEW YORK (Reuters) -Prosecutors began a U.S. corruption trial on Monday by accusing a former Goldman Sachs banker of seeking to make millions of dollars laundering money looted from Malaysia’s 1MDB sovereign wealth fund.

Roger Ng, Goldman’s former head of investment banking in Malaysia, is charged with conspiring to launder money and to violate an anti-bribery law. He has pleaded not guilty and Ng’s lawyer has called him a “fall guy” for one of the biggest financial scandals in Wall Street history.

“The defendant saw an opportunity to make millions of dollars by cheating, and he took it,” the prosecution said in an opening statement on Monday.

The trial in Brooklyn federal court could last up to six weeks.

Prosecutors are likely to argue that Ng helped two co-conspirators – his former boss, Timothy Leissner, and Malaysian intermediary Jho Low – launder funds embezzled from 1MDB and used some of the stolen money to bribe officials in the Southeast Asian country to win business for Goldman.

Leissner, a former partner for Goldman Sachs in Asia, in 2018 pleaded guilty to conspiracy to launder money, and conspiracy to violate the Foreign Corrupt Practices Act (FCPA), in part by helping to pay $1.6 billion in bribes. He is expected to testify as a government witness against Ng.

Ng’s defense is expected to argue that he had no role in the scheme perpetrated by Low and Leissner, and that he even warned Goldman management not to trust Low. Ng’s defense lawyer Marc Agnifilo has said Leissner falsely implicated Ng in the scheme in an effort to minimize his punishment.

Leissner has yet to be sentenced.

The scandal stems from some $6.5 billion in bonds that Goldman helped 1MDB – launched by former Malaysian Prime Minister Najib Razak to spur economic growth – sell from 2009 to 2014. U.S. prosecutors allege around $4.5 billion of that money was embezzled.

U.S. authorities say Goldman earned $600 million in fees from the deals. The bank in 2020 paid a $2.3 billion fine, returned $600 million in ill-gotten gains and agreed for its Malaysian subsidiary to plead guilty in U.S. court as part of a deal, known as a deferred prosecution agreement (DPA), with the Department of Justice.

The trial could shed light on how Goldman responded to warnings of possible corruption, but the bank is unlikely to face material damage.

Low, who was indicted alongside Ng in 2018, has not been arrested by U.S. or Malaysian authorities. Malaysia has said he is in China, which Beijing has denied.
