About half a dozen soldiers took Education Minister Chaturon Chaisang into custody in a chaotic scene at the Foreign Correspondents' Club of Thailand, where he had just finished giving a surprise news conference.
The junta, which seized power Thursday, is already holding most top members of the Southeast Asian country's elected administration and has ordered the rest to surrender.
Chaturon called for elections and warned that resistance to the army overthrow could grow, which could lead to "a disaster for this country."
Before being hustled into an elevator, Chaturon said: "I'm not afraid. If I was afraid, I wouldn't be here."
The military takeover, Thailand's second in eight years, deposed an elected government that had insisted for months that the nation's fragile democracy was under attack from protesters, the courts, and finally the army.
The country is deeply split between an elite establishment based in Bangkok and the south that cannot win elections on one side, and a poorer majority centred in the north that has begun to realise political and economic power on the other.
