Prime Minister Dr Mahathir Mohamad has indicated that more BN leaders would be hauled to court, according to a news report.
Speaking at an event in Thailand, he said the Pakatan Harapan government would continue to crack down on the previous government's corruption, abuse of power and other wrongdoings.
Mahathir said Malaysia had suffered for nine years under the leadership of former premier Najib Abdul Razak.
He accused the previous administration of neglecting the people and committing wrongdoings.
“Of course, there will be more action taken against other individuals. We can't bring many individuals to court at the same time.
“We will do it one by one and focus on the former prime minister (Najib),” he was quoted as saying by Sinar Harian.
The prime minister is on a two-day official visit to Thailand.
This morning, Najib was slapped with an additional six charges, bringing the total charges against him to 38.
Last week, Umno president and former deputy premier Ahmad Zahidi was charged with 45 counts of money laundering, criminal breach of trust and receiving gratification.
Previously, Najib's former aide Isham Jalil had claimed that more Umno leaders would be dragged to court in a dragnet which he likened to the 1987 Operasi Lalang during Mahathir's first tenure as premier.
