A man in Thailand has been jailed for posting images and messages on Facebook said to be insulting to the royal family.

Computer programmer Surapak Puchaieseng is being held in a Bangkok jail for his updates which go against Thailand's 2007 Computer Crime Act which prevent citizens from posting rebellious online statements that 'jeopardise national security or cause panic.'

Thai citizens can raise complaints to the police to inform them of anti-monarchy statements they read online and once these have been logged the authorities must investigate.

New Prime Minister Yingluck Shinawatra has pledged to crack down on websites that dare to question or offend the monarchy.

Police have confiscated Puchaieseng's computers. He could now face up to 5 years in prison.
