The Office of the Public Sector Anti-Corruption Commission is expected to list the investigations - along with specific action targetting illegal buildings that are too close to Phuket's beaches, where investors have broken the law.
Suspicious property titles are likely to be scrutinised in Phuket and Phang Nga, particularly in Kathu (which includes Patong) and Kamala, Phuketwan has learned.
The anti-corruption investigation team is to join with the Department of Natural Resources and Environment to pursue falsified property and real estate documents and people who have encroached on land in public forests and erected buildings above Phuket's unique 80-metre height limit.
Beachside land and Nakkerd Hill, topped by Phuket's Big Buddha, are to be looked at closely. As much as 45 rai on the hill is claimed by former Phuket officials or their relatives.
The joint investigations are to be conducted by the Secretary of the Public Sector Anti-Corruption Commission, Colonel Dusadi Arayawut, and the Permanent Secretary of the Natural Resources and Environment Department, Chote Trachoo.
Both men were on Phuket today and preparing to make a major media statement.
The investigation comes with a visit to Phuket by Prime Minister Yingluck Shinawatra and her Cabinet just 10 days away.
