Thai caretaker Labor Minister Chalerm Yoobamrung on Monday threatened to crack down on protesters at any rally site when they are gathering in small numbers, the Nation newspaper reported. In his capacity as chief of the government-run Center for Maintaining Peace and Order, Chalerm said action would be taken against protesters because protest leader Suthep Thaugsuban had gone back on his promise to rally only at certain sites. In the morning, Suthep led several thousand protesters to besiege the Government House to prevent caretaker prime minister from returning to work there. Chalerm on Sunday said police forces would be deployed from Monday to reclaim five protest sites in Bangkok from protesters, including the one near the Government House. Another group of protesters also entered the premises of the Education Ministry on Monday and forced officials there to stop work and go home.
