Station executives held several demonstrations in Sanam Luang to protest the junta's ban against the station's broadcasts. In one demonstration, 1,800 police in riot-gear surrounded approximately 1,500-3,000 protestors and attempted to dismantle PTV's protest stage. The operation was an implementation of security operation plan Pathaphi 149, which was designed to protect the army from public rallies. However, the police backed off after the protesters threw plastic bottles and yelled at them. PTV executives asked the demonstrators not to attack the police. Station executives vowed to stage weekly Friday rallies. Junta chief Sonthi Boonyaratkalin vowed to prosecute any former Thai Rak Thai leaders if they provided financial support for the rallies.
