The tragic event that triggered a national discussion occurred at a birthday party on the night of September 6 when highway police officer Pol Major Siwakorn Saibua was shot dead.
The shooting reportedly stemmed from an argument over a promotion. According to eyewitnesses, Praween’s alleged henchman, Thananchai Manmak, approached the dining table and opened fire on Siwakorn.
Praween is well known for his frequent parties and the people who attend them: Police, government officials and local celebrities. He also runs a business that bids for many government projects.
Praween surrendered to police on September 7 and was detained on September 9.
Investigators opposed granting him bail because he had been a "kamnan" (sub-district headman) for nine years. As a kamnan, he had the authority to arrest or conduct an investigation in areas under his control. He also has close ties with police officers in many other areas.
