From the BBC:

A Swiss man has been jailed for 10 years after pleading guilty to charges of insulting the Thai king.

Oliver Jufer, 57, was arrested last December after drunkenly spray-painting portraits of King Bhumibol Adulyadej in the northern city of Chiang Mai.

Earlier this month he pleaded guilty to five charges under Thailand's draconian lese majeste law. ...

Jufer, who had faced a maximum sentence of 75 years, has lived in Thailand for more than 10 years.

He was recorded on surveillance cameras defacing the portraits on the king's 79th birthday.

Earlier he had tried to buy alcohol but been refused, since such sales are sometimes banned on important days. King Bhumibol, the world's longest-serving current head of state, is a very popular figure in Thailand.

The Beeb corro says the Thai media are staying far, far away from this story.
