PETALING JAYA - Malaysian police has confirmed that a raid on the office of Malaysian Anti-Corruption Commission (MACC) deputy public prosecutor (DPP) Ahmad Sazilee Abdul Khairi took place on Saturday amid reports it was related to the investigations into the troubled 1Malaysia Development Berhad (1MDB) state investment company.

The raid was confirmed by Special Branch director Datuk Seri Mohamad Fuzi Harun, although he denied that his officers were involved.

"We are not involved as the investigation on 1MDB is led by the Criminal Investigation Department (CID). I can't comment much on the articles that were published on the online portals but one thing I know is, the facts are wrong," he told The Star on Sunday.

According to a source, police first raided Ahmad Sazilee's home in Putrajaya and later his office at the MACC's Special Operations Division at about 8pm on Saturday.

Files on 1MDB and its former subsidiary SRC International as well as laptops were seized.

The Malay Mail Online had reported that some 12 police personnel were involved in the two-hour raid on Ahmad Sazilee's MACC office on Saturday. According to the news portal, Ahmad Sazilee is an Attorney-General's Chambers officer who was seconded to the MACC to give legal advice on a probe related to SRC International.

Ahmad Sazilee, along with two others linked to agencies in the special task force probing 1MDB, had earlier been detained by police. They were former MACC advisory board member Tan Sri Rashpal Singh and Attorney-General's Chambers (AGC) finance and anti-money laundering secretariat member Jessica Gurmeet Kaur.

Malaysian police chief Tan Sri Khalid Abu Bakar has said the three were detained to assist police in investigations involving the editor of the Britain-based whistleblower website Sarawak Report, Clare Rewcastle-Brown.

The MACC, the AGC, the police and Bank Negara Malaysia make up the special task force probing allegations of graft and financial mismanagement in 1MDB.

The fund's advisory board is chaired by Prime Minister Najib Razak and has debts of over US$11 billion (S$15 billion). A Wall Street Journal report last month said that investigators in the 1MDB probe had traced US$700 million in funds deposited into bank accounts belonging to Najib.

The Malaysian police have said they are investigating alleged leaks of official information on the probe to foreigners.
