Security 
pledge after Thai 
murders

David Miller, 24, a Leeds University graduate, and Hannah Witheridge, 23, were found battered to death on a beach on Koh Tao last week.

Deputy prime minister General Prawit Wongsuwan told reporters he has ordered the Interior Ministry, Bangkok’s city government and police to install surveillance cameras and improve lighting.

He said authorities were urgently investigating the case, adding that additional police and soldiers are being sent to help the murder investigation.

Police on Wednesday refused to comment on claims they were “close to making an arrest” in connection with the murders.

Detectives were reportedly trying to trace a man who left Koh Tao the day the bodies were discovered.

The man was said to be in the capital Bangkok, and police were reported to believe at least three men were involved in attacking the young Britons.

Mr Miller, from Jersey, and Miss Witheridge, from Great Yarmouth, Norfolk, were found with severe head wounds on the island’s Sairee beach on September 15.

A bloodstained garden hoe, believed to be the murder weapon, was found nearby.

Post-mortem examinations revealed that Ms Witheridge died from head wounds while Mr Miller was killed by severe blows to the head and drowning. Around 150 police have been posted to the island but are so far apparently no closer to finding the killer.
