Groups such as Cheerlung Facebook Page, the Centre for People's Protection Institute, Thai Pakdee, and the Dharma Army group, gathered to clean the walls in front of the police headquarters after protesters on November 18 splashed paint and graffiti.
On Sunday, more people will join and a team from a paint company will teach them the correct cleaning methods.
The Thai Phakdee team said that by helping to clean up many parts, all the areas in front of the police headquarters have been returned to their original state, except the BTS concrete post and some pedestrian areas. The group will help with the cleaning until 4pm on Sunday.
