Melbourne teenager Holly Bowles has died in a Thai hospital nine days after consuming a suspected methanol-tainted drink in Laos, her father has confirmed.

Methanol is a pure form of alcohol, typically found in industrial-strength products like paint stripper or petrol. It does not have a distinct smell or colour, and it’s toxic to humans.

Six people are so far dead, with the cause suspected as methanol-tainted drinks in the town of Vang Vieng, Laos.

Holly Bowles, 19, passed away in a Bangkok hospital after being on life support, bringing the confirmed death toll to six.

Thai police have confirmed the death of Melbourne teenager Bianca Jones, who became ill after drinking tainted alcohol during a backpacking holiday in Laos.

A second Melbourne teenager has died following a mass methanol poisoning incident in Laos, bringing the confirmed death toll to six. The owner of a backpacker hostel where two young Australians were staying before they fell violently ill from methanol poisoning has been detained by police for questioning in Laos.
