Cyanide poisoning was likely the cause of the deaths of six foreigners whose bodies were found in a room in a plush Bangkok hotel, with the suspected killer among the dead, Thai police said on Wednesday (July 17).
The rapid-acting, deadly chemical was found on drinking glasses and a teapot in the room at the Grand Hyatt Erawan Hotel, and interviews with relatives of the dead revealed there had been a dispute over debt related to an investment, police said.
The six were all of Vietnamese ethnicity, with two of them being U.S. nationals, and were found dead late on Tuesday (July 16).
