The order gave no reason.
The transfer came just a month before an order which promoted Asawin to a post of assistant police commissioner became effective in October.Asawin said he was not upset about the transfer.
Asawin was said to have close connection with Sondhi Limthongkul, a co-leader of People's Alliance for Democracy, and other anti-government activists. He has been known for not favouring severe measures against protesters.
However he said, "What I am worried much is about the protest as I do not want any violence to happen."
He said he did not know who will replace him. He said sarcasitically that the new boss will have better vision than him.
