The tour guide who led three Britons through the Datanla waterfalls in Vietnam has said he tried to stop them venturing towards the whirlpool that swept them to their deaths. Sisters Beth Anderson, 24, and Isobel Mackensie Squire, 19, died along with their friend Christian Sloan, 25 at the popular beauty spot in the country’s central highlands on Friday.

Dang Van Sy, 26, told police the tourists ignored him when they headed towards the dangerous area of the falls, according to local media. He said he had asked them to wear lifejackets and crash helmets, and placed all of their personal belongings in his waterproof bag. They had taken part in a common activity of lying down in the stream and letting the water move them downwards before reaching an area close to the whirlpool. “I know that place is dangerous so I shouted to ask them to stay away from that,” Sy told police, according to Tuoi Tre News. “But they ignored me, jumping down to the stream, still with their life vests. Then the man walked back to the women behind him, but he slipped into the whirlpool and was immediately swept away, down to the waterfall.”
