CSD deputy chief Prasobchoke Prommoon said Wednesday that the National Council for Peace and Order (NCPO) would hand over Mr Sombat to CSD investigators on Thursday at 10am for questioning and for charging him with provoking unrest.
Investigators from the Technology Crime Suppression Division would also question him and may charge him with violating the Computer Crime Act for using online networks to instigate unrest.
Authorities would accompany Mr Sombat to a Bangkok martial court to seek an approval to detain him for 12 days if investigators need more time to gather evidence, Pol Col Prasobchoke said, adding the anti-coup campaigner could apply for bail in the meantime.
Mr Sombat is being detained at the Army Club in Bangkok’s Thewes area after his arrest last Thursday at a house in Chon Buri province. He went into hiding from the NCPO when the coup was announced last month after posting anti-coup messages on Facebook.
Meanwhile, Mr Sombat’s 16-year-old daughter, Tharathorn, has written an open letter asking NCPO leader Gen Prayuth Chan-ocha to release her father, saying his work had contributed to the good of society and that he had done nothing wrong.
“To really return happiness to Thai society as you have been promising, I urge that you consider returning happiness to my family as well,” the letter said.
“I do not believe that my father has done anything wrong. Please help to look after him. Please let him go.”
The letter was shown to the media by Mr Sombat’s wife, Mrs Kessuda.
