Vietnam boat sinking: Human error blamed, two arrested
Human error was to blame for the sinking of a tourist boat in Vietnam which killed 12 people, including one Briton, Vietnamese police have said.
Quang Ninh police spokesman Le Thanh Binh said a valve that allowed water to come into the boat to cool the engine had been left open overnight.The vessel's captain and a crew member have been arrested.
The wooden boat was touring the Unesco World Heritage Site in Quang Ninh province when it went down.
Speaking to Associated Press news agency, Mr Binh said: "The initial police investigation showed that the man in charge of the boat engine forgot to close the valve that allowed water in to cool the engine before he, the captain and other crew went to bed."
The engine was turned off, preventing a pump from running to push the water out.
By the time the captain and crew woke to find the boat filled with water, it was too late and the vessel sank quickly, he said.
Survivors reported seeing a wooden plank on the ship ripping away at about 0500 GMT, then gushing water inundated the boat and quickly pulled it under, near Titov island.
All 12 people who died were in cabins on the boat. The other holiday-makers who did not survive were from the US, Australia, Japan, Russia, France, Sweden and Switzerland.
Another nine foreigners and six locals were rescued from the boat.
Halong Bay, renowned for its hundreds of tiny islands and freshwater swamp forests, is one of Vietnam's most popular tourist destinations.
It is near the Chinese border in the Gulf of Tonkin, about three hours east of the capital, Hanoi.
