Police have summonsed at least three people to answer charges of violating the Emergency Decree in connection with a recent gathering to demand a probe into the disappearance in Cambodia of pro-democracy activist Wanchalearm Satsaksit.
According to the Thai Lawyers for Human Rights Centre (TLHRC), Chotsak Onsoong, Matthana Atjima and another individual have been told to report to Wang Thong Lang police on Wednesday for alleged violation of the decree.
The TLHRC said one of the three claimed the charges pertains to his involvement in the June 8 rally outside the Cambodian embassy to call for investigations into Mr Wanchalearm's disappearance.
The activist was reportedly abducted near his apartment in Phnom Penh on June 4.
The June 8 activity was led by Somyot Prueksakasemsuk, activist and former editor of the now-defunct Voice of Taksin magazine, who recently petitioned the House committee on law, justice, and human rights to look into the alleged forced disappearance cases of Mr Wanchalearm and eight other pro-democracy activists.
Mr Somyot was also summonsed.
