Activist Srisuwan Janya has vowed to continue his campaign to seek an investigation into the disappearance of the historic plaque, or Mud Khana Ratsadon, after being detained for 12 hours by the military.
Security personnel apprehended Srisuwan, secretary-general of the Association to Protect the Thai Constitution, while he was waiting at the complaint receiving centre opposite Government House on Tuesday. Srisuwan had gone there to submit a petition to Prime Minister Prayut Chan-o-cha, urging him to investigate how the 1932 Siamese Revolution memorial plaque had gone missing.
He was released on Tuesday night after being detained at the 11th Army Circle from 10am to 10pm.
After his release on Tuesday night, Srisuwan said he was told by military personnel not to make any move that could stir up conflicts or prevent the country from reconciliation.
“But I insist, I will continue to urge the PM to investigate this matter. I have the right [to do] because the new Constitution has already been promulgated, he said.
