Assets Examination Committee (AEC) member Amnuay Thantara said the AOT sent their representatives to the AEC to lodge a complaint against 14 suspects for alleged involvement in the purchase of the underground power line system and 22 suspects in the CTX bomb-detection purchase.

The two cases are among 13 corruption cases the AEC is examining.

AOT president Chotisak Asapaviriya had earlier lodged the complaint with the AEC, but failed to incriminate any suspects.

Yesterday's move came after AOT board chairman General Saprang Kalayanamitr, who is deputy secretary-general of the Council for National Security (CNS), ordered the AOT to incriminate the suspects.

Among the 22 suspects in the CTX corruption case are deposed prime minister Thaksin Shinawatra, former transport minister Suriya Jungrungreangkit, Srisuk Chandrangsu the former AOT board chairman, Wichai Jungrakkiat, a Revenue Department senior official who was among five state officials fired, for his failure to collect tax in the Shin Corp sale.

Among the 14 suspects in the underground power line system are Suriya, Srisuk, General Somchai Somprasong.

Meanwhile, the Financial Institutions Development Fund, the financial-rescue arm of the Bank of Thailand, yesterday lodged a complaint against Thaksin and his wife Khunying Pojaman over the Bt772-million land purchase scandal.

AEC chairman Nam Yimyaem said he would endorse three investigative panels to start the investigation proceedings as soon as possible.

After all the panels are established, the suspects will be allowed to object to the appointment of any members of the investigative panels.

Nam said his committee has also prepared a process to have investigative panels probe Thaksin overseas.
