Six Vietnamese nationals, three men and three women, were found dead of suspected poisoning in a room in a hotel in Bangkok’s Ratchaprasong shopping district on Tuesday night.
Prime Minister Srettha Thavisin was seen arriving at the hotel where the bodies were found.
According to an initial police report, four died at a dining table and the two others in the bedroom. The bodies have been taken to the Chulalongkorn Hospital for autopsy.
There were no signs of struggle. Tea and coffee cups were found to have been used.
Police said that the room was being used by the occupants to pack their luggage before checking out. A tour guide has been taken to Lumpini police station for questioning.
The reasons behind the suspicious deaths are not yet known, but police believe that they might lie in a business conflict or it could be a cultist mass suicide. Two of the deceased hold American citizenships.
Government Spokesman Chai Wacharonke said Prime Minister Srettha Thavisin has ordered a thorough investigation, to ensure tourist confidence in public safety and to protect the image of the country.
