Chaturon Chaisaeng, former education minister, on Friday was brought from Bangkok Remand Prison to a Court Martial as officials seek further custody of him.
Chaturon, the first civilian to be tried in the Court Martial which is empowered by military junta to try civilians, resisted the junta's order to report himself. He was also charged with instigating unrest in the country and was arrested late last month.
He was seen handcuffed and in brown prisoner outfits when he arrived at the court at about 8.30am.
His sister; Thitima Chaisang, a former Pheu Thai MP, said that her brother would file bail request today.
