The six foreigners who were found dead at the Grand Hyatt Erawan Hotel in the Thai capital Bangkok on Tuesday died of cyanide poisoning, Thai police said on Wednesday.

The police said one of the deceased was suspected of having poisoned the others over a bad business investment.

"We would like to confirm that one of the six dead caused this incident using cyanide," Noppasil Poonsawas, deputy commander of investigations at Bangkok's Metropolitan Police Bureau said at a press conference.

"We are confident one of the six conducted the crime." 

Six dead in suspected poisoning at Bangkok hotel

What did the police say?

Police said traces of cyanide were found during the autopsies of the bodies as well as on the drinking cups and a teapot in the room.

"We can assume that the six died from cyanide," Chulalongkorn Hospital's Kornkiat Vongpaisarnsin told reporters, adding that results of further tests would be available on Friday.

The US Federal Bureau of Investigation assisted police with the investigation, they said. Two of the victims were US nationals.

"We found cyanide in the teacups, all six cups we found cyanide," Trirong Phiwpan, Commander of the Thai police evidence office, told a press conference.

"After [the] staff brought tea cups and two hot water bottles, milk and tea pots... one of the six introduced cyanide."

Through investigations with relatives, the police said they also found out the group had a dispute over debt related to an investment.

What do we know about the deaths?

Thailand's Foreign Ministry said in a statement that the dead were reported to be two American citizens of Vietnamese origin and four Vietnamese nationals.

The three men and three women were aged between 37 and 56, and included a husband and wife who, along with two others, had invested about 10 million baht ($278,000) in a new hospital in Japan. Citing information obtained from relatives, Bangkok deputy police chief Noppasin Punsawat said this transaction could have been a motive.

The Thai newspaper Matichon said that five bodies were found inside a room and one was found outside.

Bangkok police chief Thiti Sangsawang said that there were no signs of a struggle and that investigators suspected the six people had been poisoned.

Thai Prime Minister Srettha Thavisin went to the site of the incident in the evening but did not provide any additional information.

Police said that officers found the bodies of six deceased foreign nationals at the hotel after receiving a call from staff reporting that there had been deaths.

Thiti said that all six were supposed to check out on Tuesday and that their luggage had been packed.

He said that food had been ordered from room service but was left uneaten.

"What we can prove now is that they are not dead from suicide but from the killing of others," he had initially added, saying they were looking for a seventh person who was connected to the group.

Government fears damage to tourism

The Grand Hyatt Erawan is located in a popular tourist area known for luxury shopping and restaurants.

Srettha ordered a swift investigation to minimize damage to the tourism sector.

"The prime minister has ordered all agencies to urgently take action to avoid impact on tourism," the Thai government said in a statement.

More than 28 million foreign tourists visited Thailand last year, spending 1.2 trillion baht ($33.71 billion, €30.9 billion) in the country.

Thailand's government expects some 35 million foreign arrivals this year. It has provided longer visa stay periods and waivers for several nationalities.
