Those under suspicion of being involved in deception fell into four groups, said Prasart Pongsivapai, a commissioner with the National Anti-Corruption Commission, which has now joined the investigation.
The four areas involving officers under investigation were:
.. Interior Ministry officers
.. Land Department officers
.. National Parks, Wildlife and Plant Conservation Department officers
.. Community leaders
The Three Dolphins Co title - on which the renowned Trisara resort now sits - is being looked at especially closely with Commissioner Prasart and a second commissioner, Narong Rathamarit, spending three days on Phuket collecting evidence.
The meeting yesterday - partly a briefing for staff and also an opportunity for the media to catch up on progress in the case - was held at Sirinath National Park, south of Phuket International Airport.
Officers from the Department of National Parks, Wildlife and Plant Conservation listened with interest to the update. As well as the NACC, the Department of Special Investigation is also involved.
Khun Narong said a new law was being suggested to remove all the problems caused by Thailand's sor kor one land titles that caused confusion and could be applied at a much larger scale in the wrong areas.
