A former special officer to Najib Abdul Razak was today remanded for seven days to assist in MACC's probe into 1MDB.

It is understood that the 42-year-old 'Datuk' was arrested at the MACC headquarters about 9.45pm last night, where he had gone to have his statement recorded.

At the court, the MACC prosecutors had requested for a seven-day remand, but the suspect, however, pleaded against it, claiming he had "health issues". 

He also pledged to accord full cooperation to MACC. 

Magistrate Shah Wira Abdul Halim granted MACC's application for remand until Sunday, July 1.

It was reported over a year ago that a company owned by the suspect had received RM2 million from the personal account of former prime minister Najib, which allegedly came from SRC International, a subsidiary of the embattled 1MDB. 

The suspect was also the co-owner of the company which developed Najib's own mobile app, released about two years ago.
