The Chumphon Provincial Court read the verdict on Thursday (April 23).
Poomjai, 41, and five followers had published a video clip of their fishing expedition in Mu Koh Chumphon National Park in August 2019, in violation of the National Park Act BE 2504 (1961).
The six defendants were found guilty and were sentenced to four years in jail and Bt40,000 fine each. However, as all the defendants confessed to their crime, their sentences were halved to two years' jail and Bt20,000 fine each.
The court, however, suspended the sentence. The defendants must report to probation officers every two months and perform 36 hours of community service. The court also ordered the defendants to produce a documentary video on natural resources conservation and publish at least two clips, minimum 10 minutes long via social media to reach the public.
