In their tens of thousands, anti-government protesters cheered and chanted into the night in central Bangkok on Thursday (October 15).
This is a show of mass defiance to a ban on demonstrations designed to end more than three months of anti-government action.
The protests are aimed at the king and the prime minister, in the biggest challenge for years to an establishment long dominated by the army and the palace.
As night fell, they chanted for the release of some 40 activists arrested this week.
Some also called out insults against the king - behavior which until recently was almost unheard of, in a country where the constitution says he must be revered.
Protests over the last three months have been largely peaceful.
But in one incident on Wednesday (October 14), police pushed jeering protesters away from a motorcade carrying Queen Suthida.
Overnight, the government banned political gatherings of five or more people.
The publication of news and online information that could threaten national security was also banned.
Police have made a number of new arrests - a student leader, a protest leader and a rights lawyer. They or their representatives all say they face charges over comments in previous demonstrations and speeches.
Those marching on the streets want a new constitution, and a reduction in the powers of the king.
