PUTRAJAYA, Malaysia, May 24 (Xinhua) -- Former Malaysian Prime Minister Najib Razak, who is facing a corruption probe, turned up at the headquarters of the Malaysian Anti-Corruption Commission (MACC) Thursday morning to face the second questioning of investigators.

The former leader arrived at MACC at around 9:45 a.m. local time (0145 GMT). Wearing a black suit and sporting a smile, a relaxed Najib waved to the media before entering the building.
