Protesters began blocking roads to the intersection at 3.30pm, after the Ratsadon pro-democracy group yesterday announced a switch of venue from the Constitutional Court in Lak Si district.
Rally organisers set up a mock court to ridicule the Constitutional Court's ruling that Prayut has not violated the charter by staying on in his Army residence.
The protesters are demanding Prayut’s removal, a new Constitution and reform of the monarchy.
Meanwhile core protest leader Panasya “Rung” Sitthijirawattanakul has reportedly received a fresh summons from the Technology Crime Suppression Division (TCSD) to hear charges of lese majeste and computer crime on December 9.
The charges reportedly stem from a police complaint filed by royalist composer Nitipong Honark on November 20.
