The activist’s parents warned they would take legal action against people who had signed a controversial letter on May 2 by the Thai Ambassador in Seoul, which was sent to the chairman of the May 18 Memorial Foundation that gave Pai the Gwangju Prize for Human Rights this year.

On Tuesday Jatupat’s parents Wiboon and Prim Boonpattararaksa sent a letter to the Foreign Ministry seeking an apology from the Thai ambassador and correction of information they said was inconsistent with the facts.

The couple expressed concern in the letter that the false statement in Jatupat’s case might result in misunderstanding and provoke insults and hatred for their son.

As of press time, Jautpat’s parents, which were in South Korea representing the activist at the awards ceremony, could not be reached for comment on when they would take legal action if the ministry did not respond to their demands.

Jatupat, 25, was charged with lese majeste and computer crimes last December for sharing a BBC article deemed insulting to the Thai monarchy.

He remains in prison to date after the court had rejected all his nine bail requests.
