The 10 officers included investigators and their superiors responsible for the case, said Pol Lt Gen Sanit Mahathavorn, acting chief of the Metropolitan Police Bureau. It also looked into the investigators’ decision not to charge Mr Vorayudh with drink-driving and whether they had deliberately stalled the case. National police chief Pol Gen Chakthip Chaijinda in March assigned Pol Lt Gen Sanit to probe the investigators at Thong Lor station over their slow handling of the high-profile case. The preliminary investigation into the Thong Lor officers' conduct indicated several “flaws and irregularities” in their handling of the Red Bull heir’s case but no details have been released. Mr Vorayudh, who is now 31, challenged the prosecution and his request for the police to question an additional six witnesses was granted by the Office of the Attorney-General.
