Plaque installed by protesters at Sanam Luang on Sunday 'missing'

On Sunday morning, the main organisers of the weekend protests, the United Front of Thammasat and Demonstration group, had installed a brass Khana Ratsadon (People's Party) memorial plaque, similar to the plaque commemorating the 1932 coup -- which subsequently went missing in 2017. The 1932 revolution paved the way for Thailand changing from an absolute monarchy to a constitutional monarchy.

At around 5am on Monday, the plaque was found to have been removed from Sanam Luang. Officials had reportedly closed the Sanam Luang area at 4pm on Sunday.
The protest leaders had cursed that those who removed this plaque would lose their positions, acceptance and sexual performance.
Tens of thousands of people from across the country attended the peaceful pro-democracy protests on the weekend.

This morning, several people visited the site where the plaque had been installed to take photos.

An unknown man broke up some concrete near the plaque site with a stone and placed symbolic articles associated with the pro-democracy protests there. They comprised roses, photos of the protest leaders and a cap with three-finger symbol.
