The Office of the Attorney General (OAG) is finalising the case of the leaked audio clip between Cambodian Senate President Hun Sen and former prime minister Paetongtarn Shinawatra.
Watcharin Phanurat, OAG deputy director-general, said on Tuesday the office has ordered the Cyber Crime Investigation Department 1 to supervise the case, with him leading the probe committee.
Investigators have already questioned numerous witnesses, including Ms Paetongtarn and one individual who reported on Hun Sen’s usage and behaviour on Facebook.
The authenticity of the audio clip does not need to be verified, he said, as Ms Paetongtarn was ruled ethically unfit to continue serving in her post by the Constitutional Court.
The OAG’s case on the audio clip is separate from that conducted by the Constitutional Court, according to Mr Watcharin.
He said the OAG’s investigation focuses on whether Hun Sen had any intention to instigate chaos or turmoil among Thais and if he violated Section 116 of the Criminal Code and the Computer Crime Act.
The investigation is set to finish in the coming weeks before it is submitted to the attorney-general, with only that figure able to decide on the accusation against Hun Sen, as it is considered an extraterritorial case.
The OAG may also probe another case to decide if Hun Sen’s offences involve terrorism and harm against the public, leading to the loss of life and property.
Police complaints to that effect have been filed by both the people and public offices in many areas in Thailand, said Mr Watcharin.
