Thai police investigating the murders of two British tourists say they are ‘close to making an arrest’.
Hannah Witheridge, 23, and David Miller, 24, were found dead on the island of Koh Tao on September 15.
Police are now trying to find a man who left the island that day and is thought to be hiding in the Thai capital Bangkok, reports the BBC.
At least three men are thought to have been involved in the attack on the tourists.
According to post-mortem examinations, Ms Witheridge, from Great Yarmouth, Norfolk, died from head wounds while Mr Miller, from Jersey, was killed by blows to the head and drowning.
Two items – a heavy garden hoe and a piece of wood – have been identified as the murder weapons.
Police have now questioned the owner of the bar where Mr Miller and Ms Witheridge were reported to have been involved in an argument shortly before they were killed, BBC’s south-east Asia correspondent, Jonathan Head said.
He added: "His brother has been identified as a man seen running on CCTV pictures taken near the crime scene – he was also questioned for three hours.
"Both men gave DNA samples, but have not been charged. The police say they are now searching for another man connected to the family who fled to Bangkok shortly after the crime."
A £4,000 reward has been offered for information leading to arrests.
