PHUKET: Two government agenciest face prosecution for ''not doing their jobs'' as investigations into several key cases of alleged encroachment on public parklands draw to a close.

The Director General of the Royal Forest Department, Theerapat Prayurasiddhi, said yesterday on a visit to Phuket that information about the role of government officers had been passed to police.

He said that the two sor kor one title deeds held by Three Dolphins covering more than 100 rai on the edge of Sirinath National Park on Phuket could not be genuine in covering such a large tract of land.

The highly-regarded Trisara resort sits on the property in dispute. Khun Theerapat said it was ''impossible'' for the two deeds to cover more than 100 rai.

Investigations were also continuing into how a picturesque public waterfall in Patong, visited by HM The King in the 1950s, became surrounded by condominiums and other construction.

Khun Theerapat, appointed after the military takeover on May 22, has previously told Phuketwan that he would be aiming to restore all land where encroachment can be proven to the public.

He was accompanied yesterday by the department's Chief of Preservation-Protection, Cheewapab Cheewatam, a former director of Sirinath National Park.

According to the Bangkok Post, the Land Department has demanded that the Department for National Parks, Wildlife and Plant Conservation produce evidence that it illegally issued title deeds for Sirinath instead of making accusations through the media.
