Corrections Department chief Suchart Wongananchai said Amphon Tangnoppakhun died at 9am Tuesday after being sent from the prison to a prison Hospital. He had been suffering from stomach pain since May 4.
Suchart said he was waiting for autopsy to know the cause of death.
Meanwhile his lawyer, Anon Ampa of Rassadornprasong Law Office said on his Facebook page, that it was believed that Amphon, known as Akong or grandpa in Chinese, died from cancer.
Amphon was arrested on August 3, 2010 and was convicted on November 23 last year. Anon recently withdrew his client’s appeal, as the elderly man wished to ask for a royal pardon.
