Singapore police is examining Goldman Sachs Group Inc.'s relationship with the Malaysian state investment fund at the center of global money laundering probes, Bloomberg reported on Friday.

The Commercial Affairs Department, the police's economic crime unit, and city prosecutors have interviewed current and former Goldman Sachs executives who worked on bond offerings from 1Malaysia Development Bhd., the report said citing people with knowledge of the matter.

Investigators are also looking into the firm's links with Malaysian financier Low Taek Jho, who the U.S. has alleged controlled a plot to siphon billions of dollars from the bond proceeds, the report said.

Neither Goldman Sachs nor its current or former employees have been publicly accused of criminal offenses or charged in relation to the fund, whose dealings have sparked probes in Singapore, Switzerland and the U.S.

In July, Yeo Jiawei, a former banker serving the jail term in Singapore's probes linked to 1Malaysia Development Bhd., admitted to money laundering charges.

1Malaysia Development Berhad is a government investment company that was formed in 2009 under Malaysian Prime Minister Najib Razak to attract foreign flows.

Investigators are trying to find out whether money flowed through and around 1MDB and illegally into personal accounts. Some of the money is alleged to have ended up with Najib and his family.
