Chatupat, also known as Pai Dao Din, and other students took to the stage on July 31 to talk about the charter. The Khon Kaen police had summoned them to face the charges on August 18.

Chatupat, however, also faced other charges for violating the referendum law and was detained in Phu Kieo district’s prison.

His attorney, Arnon Nampa, postponed the police meeting to yesterday. Arnon said Chatupat was sick from going on a hunger strike in Chaiyaphum.

After they were booked, the six read out a statement condemning the state for restricting their right to express their views.

They called on society to protest against the ban on public gatherings and the trial of civilians in military courts.

Yaowalak Anupan, their lawyer, said the six suspects denied the charges, saying they were at liberty to speak about the constitution, which is an important matter to everyone.

She said the police also told her that more people would be hit with the same charges today.
