In a Facebook post on Saturday, the group leader Warong Dechgitvigrom cited the United Nations Commission on Human Rights (UNCHR)'s concerns about at least 35 people, including a 16-year student, facing lese majeste charges.
"We would like to ask the Foreign Affairs Ministry to clarify to the UNCHR that the abovementioned people are aiming to encroach on the monarchy," he said.
"Meanwhile, parents should take good care of a 16-year student because he has little experience in politics and he may be a victim of bad politicians' moves to benefit indirectly."
