A London law student was among at least 20 people killed in a bomb blast at a popular Hindu shrine in Bangkok.
Vivian Chan, 19, is thought to have been travelling with a friend who was also killed in the bombing which rocked the Thai capital on Monday.
The Foreign Office said on Tuesday it could not confirm whether Chan was the British national from Hong Kong whose death had earlier been confirmed by Foreign Secretary Philip Hammond.
Professor Peter Crisp, Dean of Law School at BPP University in London, said: "Everyone at BPP University is devastated to hear of the loss of one of our students, Vivian Chan Wing Yan, in Bangkok yesterday.
"Our thoughts are with Vivian's family and we are currently working to support them in any way we can."
Prime Minister David Cameron posted on Twitter: "Deeply saddened to hear a British national was killed in the horrific Bangkok bombing.
"My thoughts are with her family and all those affected."
Thai authorities are searching for a man caught on security cameras leaving behind a rucksack at the popular attraction, which is in an area well-used by foreign visitors.
More than 100 were injured by the blast.
Five of the victims have so far been identified as Thais, four as Chinese - including two from Hong Kong - two from Malaysia and one from Singapore.
No one has yet claimed responsibility for the bombing, which bears none of the hallmarks of the Muslim separatists who have been fighting a long insurgency in the south of the country.
