Four people had already died following the suspected poisonings – an Australian teenager, as well as two Danish women and a 56-year-old US citizen.
A British tourist being treated after a suspected mass methanol poisoning in Laos has died, according to UK officials.
Simone White, 28, from Orpington, Kent, fell ill after reportedly drinking “free shots” from a local bar in Vang Vieng – a resort popular with backpackers.
Four people had already died following the suspected poisonings – an Australian named Bianca Jones, 19, from Melbourne, as well as two Danish women in their 20s and a 56-year-old US citizen.
They are believed to have consumed drinks tainted with methanol, which is sometimes added to mixed drinks as a cheaper alternative to alcohol, but can cause severe poisoning or death.
“We are supporting the family of a British woman who has died in Laos, and we are in contact with the local authorities,” the UK’s Foreign, Commonwealth and Development Office (FCDO) said in a statement.
The FCDO said it was also providing consular assistance to other British nationals hospitalised in the incident, as well as their families.
Ms White was an associate lawyer specialising in intellectual property and technology and worked at the London office of the American law firm Squire Patton Boggs.
Her work involved general commercial matters, and contentious and non-contentious intellectual property law issues, according to the firm’s website.
Bethany Clarke, a friend of Ms White and a healthcare worker, also from Orpington, said a group of six people had been taken to hospital after drinking from the same bar.
She posted on a Laos Backpacking Facebook group to warn other travellers after the group fell ill.
“Urgent – please avoid all local spirits. Our group stayed in Vang Vieng and we drank free shots offered by one of the bars,” she wrote.
“Just avoid them as so not worth it. Six of us who drank from the same place are in hospital currently with methanol poisoning.”
‘Every parent’s very worst fear’
Australian Prime Minister Anthony Albanese confirmed to his country’s parliament that 19-year-old Bianca Jones had died after being evacuated to a Thai hospital from Vang Vieng.
Thai authorities confirmed Jones had died of “brain swelling due to high levels of methanol found in her system”.
Her friend Holly Bowles, also 19, remains in hospital in neighbouring Thailand, Mr Albanese said.
Australian officials said “several foreign nationals” had also been victims of methanol poisoning
“This is every parent’s very worst fear and a nightmare that no one should have to endure,” Mr Albanese said.
“We also take this moment to say that we’re thinking of Bianca’s friend Holly Bowles who is fighting for her life.”
