The Anti-Corruption Organisation of Thailand (ACT) yesterday submitted a letter to the prime minister calling on him to disclose details of the investigation into the alleged mishandling of the hit-and-run case against Red Bull scion Vorayuth "Boss" Yoovidhya.
The ACT's open letter urged the government to disclose the detailed results of a fact-finding committee chaired by former National Anti-Corruption Commissioner Vicha Mahakun.
The group called on the government to urgently punish the wrongdoers to regain trust from all sides.
The open letter also said the case received a lot of attention from the public due to alleged corruption by police and public prosecutors.
The ACT said delays would further damage the image of both the government and the justice system and vowed to monitor the case until the end.
The fact-finding committee earlier submitted a full report to the prime minister but details of the alleged corruption and names of the wrongdoers were not made public.
The five-point proposal made by the Vicha committee were to: Revive the hit-and-run case; take legal and disciplinary action against people found in the wrong; look into the ethical conduct of those whose roles were not clear; redefine the role and authority of supervisors; and give the committee another month to make recommendations on legal reform.
The committee suggested that a single deputy attorney-general should not have been assigned to handle both a complaint filed by Mr Vorayuth and also asked to decide whether or not to indict him at the same time.
In its report, the Vicha committee identified eight groups of people who played a role in the controversial dropping of charges against Mr Vorayuth.
Deputy Prime Minister Wissanu Krea-ngam said various people, including police officers, public prosecutors, lawyers and civilians, had been guilty of misconduct in their handling of the case.
The Royal Thai Police, for instance, would be asked to probe the misconduct said to have been committed by its officers who were involved in the case.
