Acting Prime Minister Niwattumrong Boonsongpaisan yesterday fled from protesters to hide in a "safe house".
He is scheduled to leave for Chiang Rai today, a source close to him said.
Niwattumrong fled from an Air Force auditorium near the Air Force Officers' Club after protesters led by the People's Democratic Reform Committee broke into the compound.
The acting prime minister was meeting with the Election Commission on preparations for the new vote.
The source said the acting prime minister kept a low profile in the safe house and did not go to work at his temporary office at the Defence Ministry.
He is scheduled to visit the people affected by the earthquake in Chiang Rai.
