Viboon, Prim and Promporn Boonbatararaksa, respectively the father, mother and sister of the activist better known as “Pai Dao Din”, will attend the ceremony on Thursday to receive the award, which comes with a US$50,000 (Bt1.7-million) prize.

Jatupat, who was arrested for alleged violations of the Computer Crime Act and the lese majeste law, was recognised by the committee of the May 18 Memorial Foundation for his courage in fighting for human rights in Thailand.

Viboon wrote on his Facebook page yesterday that Jatupat “is deprived of his right to bail and other human rights including the chance to represent the Thai people in receiving such as honourable award because the Thai government took a different stance”.

Jatupat is the youngest person and the second Thai to receive the award.

The first Thai was Angkhana Neelapaijit, a National Human Rights Commission member well known for campaigning against forced disappearances.
