A statement issued at the meeting in Sirinath National Park said police had been asked to prosecute Three Dolphins (owners of Trisara) Pullman Phuket, Naithon Beach Ltd, Surachai Laosaicher and Chomchanok Sutamma.
The Three Dolphins case has been accepted for investigation by the Office of the Public Sector Anti-Corruption Commission, with eight plots involving nor sor sam kor titles allegedly expanding to cover 136 rai.
The forwarding of dossiers to police by the Natural Resources and Environment Ministry is the latest step in a drawn-out investigation over alleged encroachment of hundreds of rai of public parkland on Phuket.
Today's meeting also heard that eight other properties, reckoned by the Natural Resources and Environment Ministry to be illegal in parts, were deemed by the Land Titles Office to be legal. The Justice Ministry had been called in to resolve the dispute.
The eight properties involving 52 plots alleged to be illegal are: Peninsular Spa and Resort, Central and City Development (Centra Grand West Sand Resort & Villas Phuket), Landstate Co (Bang Tao Beach Resort) , Pavilion Beach Resort, Layan Phuket Limited (Bundarika Villas & Suites Phuket), Suchada Sangsuwan, La Colline Villa Development and ''Bernard's house'' (Bernard Gauthier).
In some cases, owners have protested their innocence. The investigators have said that any deception may be historical, with detectives being required to pinpoint how and when the alleged frauds were perpetrated and by whom.
