The police are expected to record a statement from a Bank Negara Malaysia director and several staff tomorrow in connection with a letter leaked to The Wall Street Journal.

According to a source, a special team from the Bukit Aman police headquarters would quiz the director of the financial intelligence department, which looks into cases of money laundering.

“This will be part of the process to determine if the letter leaked to The Wall Street Journal is authentic,” he told Malaysiakini.

The special police team is in charge of high-profile cases.

Following this, the source said statements would also be recorded from members of the Public Accounts Committee (PAC).

“If the letter is found to be genuine, we need to find out how it was leaked,” he added.

Earlier, inspector-general of police Khalid Abu Bakar told Malaysiakini that Bank Negara staff would be quizzed over the issue.

He also did not rule out the possibility of PAC members being questioned, saying that statements would be recorded from all those whom the police believe could shed light on the case.

After the letter, which is under the Official Secrets Act (OSA), was revealed last week, Prime Minister Najib Abdul Razak said Bank Negara governor Muhammad Ibrahim lodged a police report against WSJ.

However, Najib said he could not confirm if the letter was genuine.

WSJ, which has been accused of being part of the campaign to oust Najib, had tweeted a copy of the letter, and this was later re-tweeted by its Asia chief editor Tom Wright.

The letter is from Bank Negara to PAC chairperson Hasan Arifin.

The document supposedly confirmed that Good Star Limited was owned by tycoon Low Taek Jho, who is better known as Jho Low.

This contradicted the government’s assertion that Good Star, which has since been dissolved, belonged to former 1MDB joint-venture partner PetroSaudi International.
