Thailand beach murders: Burmese workers confess to Koh Tao murder of Hannah Witheridge and David Miller

The two tourists were found near to where they were staying on the island of Koh Tao on September 15

Two Burmese workers have confessed to killing British tourists Hannah Witheridge and David Miller on a Thai holiday island, police have said.

Ms Witheridge, 23, and David Miller, 24, were found near to where they were staying on the island of Koh Tao, on September 15.

Major General Kiattipong Khawsamang said two of three Burmese workers questioned by police had admitted murdering the couple. He said the other man denied involvement.

Police have previously said they believe three people were involved in the attacks.

The island has a large community of migrants workers from nearby Burma, also known as Myanmar. Police have been under pressure from the government to solve the case as Thai authorities warned the killings would damage the country's tourist industry.

Earlier this week police said two suspects raped and killed Ms Witheridge while another witnessed the murder.

Last week the Royal Thai Police said they were "confident" of making a breakthrough in the case after coming under fire for their handling of the investigation.

Officers have collected 200 DNA samples from people on the island after tests carried out on Ms Witheridge’s body revealed traces of semen from two different men.

Lieutenant General Jaktip Chaijinda said police will wait for the results of DNA tests from the suspects to see if they match the samples. Those DNA results are expected by tomorrow at the latest, according to reports.

Mr Miller's father Ian has said he believes his son stepped in to help Ms Witheridge.

Post-mortem examinations revealed that Ms Witheridge, from Great Yarmouth, Norfolk, died from head wounds, while Mr Miller, from Jersey, was killed by severe blows to the head and drowning.

Around 150 police officers have been posted to Koh Tao as part of the murder investigation.
