The Myanmar embassy has asked the Justice Ministry to reopen the investigation into the murder of two British tourists on Koh Tao.
Lawyer Aung Myo Thant told the Democratic Voice of Burma (DVB) that the embassy made the request to the Thai Justice Ministry on Monday evening, on the basis the confessions by Myanmar suspects Zaw Lin and Win Zaw Htun were obtained through torture.
"The kids [Zaw Lin and Win Zaw Htun] have told the National Human Rights Commission, the lawyers, our embassy team and their parents on each occasion that they were beaten by police," he said.
"Therefore, we have requested that a special team be formed to re-investigate the case. We presented a formal letter of request to a ministry official."
Shortly after their arrest, the two suspects were taken to Koh Tao beach to re-enact the police version of the murders of the English tourists.
Aung Myo Thant said he and the embassy team met members of the Lawyers Council of Thailand, the NHRC and the suspects' parents on Monday.
A representative of the NHRC called on police to answer the allegations of torture during the interrogation process, but the police failed to show up at the meeting, said Myanmar embassy team member Kyaw Thaung of the Myanmar Association in Thailand.
"The NHRC asked the Thai Lawyers Council and ourselves to present any information we had," he told the DVB.
"They also requested any evidence that contradicts the DNA tests. We exchanged information about the details of the case."
British tourists David Miller and Hannah Witheridge were bludgeoned to death on the island of Koh Tao in the early hours of Sept 15. Witheridge was also raped.
Zaw Lin and Win Zaw Htun were arrested two weeks later.
