PETALING JAYA (THE STAR/ASIA NEWS NETWORK) - Two more Malaysian anti-graft officers were brought in by police on Tuesday for questioning over leaked information in the probe over the troubled state investment fund 1Malaysia Development Berhad (1MDB).

The officers, identities withheld, were summoned to the Putrajaya police district headquarters at about 5pm on Tuesday.

"One of them was questioned for two hours while the other had just started getting his statements recorded," Malaysian Anti-Corruption Commission (MACC) strategic communications division director Datuk Rohaizad Yaakob said, when contacted by The Star Online.

It is learnt that the officers, attached to the Special Operations division, were directly involved in the probe.

Six MACC officers have so far given their statements to the police.

The MACC, the Attorney General's Chambers, the police and Bank Negara Malaysia make up the special task force probing allegations of graft and financial mismanagement in 1MDB, which has debts of over US$11 billion (S$15 billion). The Sarawak Report whistleblower website had previously published a draft charge sheet purportedly leaked by the investigation team on 1MDB.

On Monday night, Special Operations division officer Tuan Roslan Tuan Mat had his statements recorded.

Earlier, Criminal Investigation Department officers spent two hours questioning special operations division director Datuk Bahri Mohd Zin at the MACC headquarters in Putrajaya, while head of the forensic division, Datuk I.G. Chandran, was questioned for three hours at the MACC Academy in Kuala Lumpur.

On Saturday, police searched the home of MACC deputy public prosecutor Ahmad Sazilee Abdul Khairi and his MACC office.

Documents on 1MDB and its former subsidiary SRC International as well as laptops were taken away by police.

This came after the arrest of former MACC advisory board member Tan Sri Rashpal Singh and Attorney-General's Chambers finance and anti-money laundering secretariat member Jessica Gurmeet Kaur. They were detained to assist police investigations on the alleged leak.

On Monday, a senior MACC enforcement officer from its intelligence unit had also lodged a report at the Putrajaya police headquarters, denying that MACC had leaked information pertaining to the 1MDB probe.
