Tan Thaugsuban and three other suspects are accused of encroaching on forestland in Surat Thani’s Samui district, illegally occupying plots and building on them.
The Department of Special Investigation (DSI) launched a probe into the alleged encroachment and found there were grounds to believe that Tan and his accomplices committed wrongdoing.
DSI officials brought the investigation report to public prosecutors at the Department of Special Litigation yesterday.
The chief of the department, Winai Damrongmongkhonkul, said the suspects would be summoned to hear the order on January 15.
Tan’s lawyer Wiroj Phumsirisawas said the case was politically motivated. He insisted his client held the land plots legally, because he possessed the land-title deeds.
“There is also evidence of purchase,” he said.
Samart Ruangsri, one of the alleged accomplices, said he sold the land plot to Tan.
“If the DSI thinks I illegally obtained the land title deeds, it should look into all the other land plots around mine too,” he said.
