Six people found dead in Bangkok luxury hotel in suspected poisoning

Six people have been found dead at a luxury hotel in central Bangkok, in what authorities say could be a case of poisoning.

The bodies of three women and three men were found inside a hotel suite on the fifth floor of the Grand Hyatt Erawan hotel by a hotel worker late on Tuesday afternoon.

They were Vietnamese, and two had American citizenship, the Thai prime minister, Srettha Thavisin, said.

It is assumed the six had been dead for at least 24 hours before their bodies were discovered, police said, adding that the room had been locked from the inside, but that the staff member was able to enter through a separate door.

Police shared images of hotel food found in the suite, which was still sealed in clingfilm and appeared to be untouched. However, six cups did appear to have been used, police said.

Srettha said he had met the Vietnamese ambassador to discuss the matter and has ordered a swift investigation into the case.

The deceased had been booked to stay at the hotel as a group of seven people, but only five checked in, police said, while six people had been found dead. Police said they were now searching for the seventh individual.
