SEAN McANNA, originally from Glasgow, posted messages on Facebook last night claiming his life was in danger because he knows who killed backpackers David and Hannah a week ago.

He posted: “Thai mafia are trying to kill me. Please help me.” A few minutes later he accused a local bar owner of being responsible.

“He said the island is run by the Thai mafia and he knew the identities of the killer.

“He was frightened for his life and felt he needed help from anyone he could and social media was his best option.

“His mum and sister contacted Scottish and Thai police and he is now safe.

“He will be leaving as soon as he can. We don’t have anymore information at the moment.”
