Prayut also thanked people who avoided participating in the protest, while expressing regret over damage to properties and trouble caused to people near the protest sites, Anucha added.
"Prayut emphasised that using violence during the protest was against the law, such as Communicable Disease Act and the state of emergency," Anucha said.
"People who hold or participate in such gatherings, which raise the risk of Covid-19 infection, would face two years' imprisonment or THB40,000 fine or both."
Anucha also asked protesters to propose suggestions or file complaints to the government properly and avoid using violence.
