Thailand's youth-led anti-government protests started in July to demand the resignation of Prime Minister Prayut Chan-o-cha and have also made once-unthinkable calls for reform of the monarchy.
Below are details of some of the most prominent leaders, who have been jailed pending trial, indicted or charged by police for their roles in the protests, over offences that included sedition and royal insult. Those indicted could be remanded in prison if bail is denied.
The lese majeste law prohibits criticism or insults against the king, and each offence is punishable by up to 15 years in prison.
Jailed awaiting trial
- Anon Nampa, 36, a human rights lawyer who first openly demanded reform of the monarchy at a Harry Potter-themed rally in August, is being prosecuted for 21 cases, including 11 of lese majeste. He has been jailed since Feb 9 awaiting trial over protests in September.
- Parit "Penguin" Chiwarak, 22, a student activist who rose to prominence as co-leader of the United Front of Thammasat and Demonstration (UFTD) group, is being prosecuted for 32 cases of protest-related offences, 17 of which are lese majeste cases. He was jailed alongside Mr Anon.
The two have been denied bail five times since Feb 9.
