Thailand's government will not back down from prosecuting news outlets that publish "illegal" content, the defence minister has said, after the BBC's bureau in Bangkok came under scrutiny for an article about the country's new king.
The British broadcaster's Thai-language service, a relative newcomer, caused a stir when it published an article on King Maha Vajiralongkorn Bodindradebayavarangkun's personal life as crown prince.
It included details of three marriages that ended in divorce and other material that cannot be published in the Thai news media.
Thailand has strict lese majeste laws against insulting the monarchy, which carries a penalty of three to 15 years in prison.
"Whatever is illegal will be processed accordingly, no exceptions," defence minister Prawit Wongsuwan told reporters.
In the days after the article was published on December 2, the day after Vajiralongkorn ascended the throne, the BBC office in Thailand received multiple visits from the Thai army and police.
The BBC shut the office this week but continues to broadcast and publish on its website, although the link to the article about Vajiralongkorn is now blocked in Thailand.
"Officials were just doing their jobs when they searched this news agency," Mr Prawit said.
The article sparked outrage among Thai royalists. The Facebook group "V for Thailand" has been vigorously criticising the BBC, and posted the BBC's Bangkok phone number on its page, encouraging its followers to call and harass people who work there.
Thai police arrested a student on Saturday for sharing the BBC article, releasing him on bail the next day. It was the first arrest under lese majeste law since Vajiralongkorn became king.
It appeared to be the first case involving material produced by a respected mainstream media outlet, although previous cases have involved content from several foreign tabloids.
Mainstream media have had stories about the Thai monarchy censored, by blocking their websites and the voluntary stopping of distribution of editions of magazines and newspapers in Thailand, including The Economist and the International New York Times.
Critics of the lese majeste law, known as Article 112, say it is used to silence political dissidents. The military regime that took power in a 2014 coup has especially cracked down on commentary on the internet.
