The extent of wrongdoing in 1MDB is far greater than what is publicly known, revealed Dr Mahathir Mohamad today.
The prime minister drew the conclusion after being briefed by police and auditor-general Madinah Mohamad over 1MDB scandal.
"It was clear that the wrongdoing is more than what was known by the public, and by me.
"We will take action to lodge a police report. When there is an opportunity we will make the arrest, we will get the person involved in the wrongdoing," added the Pakatan Harapan chairperson.
Meanwhile, Mahathir said the government will write to US, Singapore and Switzerland to repatriate allegedly misappropriated 1MDB-linked funds.
"We will recover this money from US, Switzerland and Singapore, probably Luxembourg also. We will contact them to recover the money.
"There was no admission from the administration of Najib Abdul Razak that the money belonged to us, therefore no application to claim the funds.
"But, we want to state that the money was from 1MDB and Malaysia, we will apply to recover the funds," he added.
Mahathir noted he was unclear of the amount of 1MDB funds overseas, but he knew there was US$4.5 billion in US.
He added that it is up to the police whether to summon former prime minister Najib Abdul Razak to record a statement over the scandal.
