He said the Metropolitan Police was now cooperating with the Technology Crime Suppression Division to track down the people who posted anticoup messages as well as items seen as encouraging people to come out to protest against the junta. He said the messages violated Article 116 of the Criminal Code.
Amnuay said the first batch of arrest warrants against those who have posted such messages could be approved by the court in a few days.
He added that anyone sharing anticoup messages would also be in violation of the law and could face arrest.
He said police had taken photos of seven persons who made the Hunger Game salute during a rally on June 7 and would seek arrest warrants against them.
