Police on Saturday brought the arrested We Volunteer (Wevo) members from the Border Patrol Police Region 1 headquarters in Pathum Thani province to Dusit Kwaeng Court in Bangkok.
On Thursday the pro-democracy group, Wevo, had collaborated with prawn traders to sell their products amid the new Covid-19 outbreak in Thailand, which started from a seafood market in Samut Sakhon province.
According to witnesses, police confronted the Wevo members and said they were violating the ban on unauthorised public gatherings at Sanam Luang, where selling of products is also prohibited.
Wevo leader Piyarat Chongthep and other members were arrested by police for alleged violation of laws. They were taken to Pathum Thani province for questioning.
The activists were charged with violating the emergency decree, the Communicable Disease Act, and the Controlling Public Advertisement by Sound Amplifier Act.
