Protesters led by Phra Buddha Iassara started rallying outside the Voice TV satellite TV station at 9:20 am Monday.
The protesters arrived in five buses and several pick-up trucks.
The TV station is owned by Pantongtae Shinawatra, the son of former prime minister Thaksin Shinawatra.
The monk announced that farmers, who were rallying in front of the Commerce Ministry, would move to rally in front of the TV station as well and they would stay overnight there.
The monk said farmers were dissatisfied that the TV station had reported that the protesting farmers were not real ones but established protesters.
“So, the farmers want to show that they are the real ones,” the monk said.
The station was guarded by 20 policemen led by Pol Col Charoen Srisalak, deputy commander of Metropolitan Police Division 2.
The monk criticized the police for guarding the TV station instead of helping farmers.
The monk said police should set up a new police station at the TV station if they would like to serve the Thaksin regime.
