Thai authorities will give red shirts protesters more time to leave the area after a 3pm deadline passed, government spokesman Panithan Wattanayakorn said Monday.
The government's main focus is to convince women, children and elderly people who have received wrong information to leave the Rajprasong rally site.
Authorities will set up more checkpoints around the city to prevent more chaos, Panithan said.
Center for the Resolutions of Emergency Situation (CRES) has issued a deadline at 3pm for the red shirts protesters to leave Rajprasong rally site.
CRES has failed to say what it would do if the red shirts did not meet the deadline.
Meanwhile Prateep Ungsongtham Hata who has been known for her works in slum areas set up a stage on Rama IV road near Klong Toey populated community and called for people to join Rajprasong rally.
Police failed to convince her to move the stage as it caused more traffic congestion on the road.
