I just received the news that Ajarn Sulak Sivaraksa has been arrested for lese majeste. I don't know any details apart from what has been published in news reports on the internet. The BBC reports:
I will update the blog again if I receive any more substantial news.
One of Thailand's best-known social activists has been arrested on charges of insulting the monarchy.
Sulak Sivaraksa is often described as the founder of Thailand's movement of non-governmental organisations (NGOs).
The 76-year-old was detained in connection with a speech he made last December. He has been released on bail.

From Reuters: Arrest of Thai academic raises free speech fears
Somchai said that what Sulak had said in a public speech last December in Khon Kaen was very mild. Somchai also said the military had had a role in this by raising ultra-royalist fervour in recent weeks and this might explain why Sulak had been arrested.
Sulak was later given bail and flew to London last night for a pre-arranged engagement; he will return to Bangkok in November to fight the charge.
