The closed-door trial of an activist law student arrested for sharing an article about Thailand's new king on Facebook has begun.
Jatupat "Pai Dao Din" Boonpattararaksa was arrested in December for sharing a profile about the Thai king that was posted on Facebook by the Thai-language service of the BBC.
His arrest was the first under the country's tough lese majeste law since the new king took the throne last November.
Lese majeste, or insulting the monarchy, carries a penalty of three to 15 years' imprisonment.
The BBC article included mentions of the king's personal life when he was crown prince, including details of three marriages that ended in divorce and other material Thai news media can publish only at their own risk.
