Malaysia’s former prime minister Najib Razak is expected to face four more charges related to 1Malaysia Development Bhd (1MDB) scandal this week, the New Straits Times Online reported on Tuesday.

Quoting those with knowledge of the ongoing investigation, the New Straits Times said the four charges expected to be slapped against Najib deal with 1MDB links with International Petroleum Investment Co.

Prosecutors would hold Najib liable for his role in last year’s debt settlement between 1MDB and the Abu Dhabi wealth fund.  Najib was chairman of 1MDB board of advisors until it was dissolved in May 2016 when the Finance Ministry took over its remaining assets.

He is expected to face charges related to criminal breach of trust.

Sources said Malaysia’s Anti-Corruption Commission was looking into how the former administration had settled debt using taxpayers’ money and who authorized the payment allegedly even without the approval of the cabinet.

Najib has, so far, been slapped with 32 charges mostly linked to funds from 1MDB which he founded.
