Police investigating the apparent poisoning of a British family of five on holiday in Bangladesh, which killed a father and son, are hoping the survivors could hold the key to what happened.Rafiqul Islam, 51, a taxi driver from Cardiff, and his son, 16-year-old Mahiqul, along with three other members of their family, were discovered unconscious in a locked room by police officers on Tuesday.
The father and son could not be saved, while Rafiqul Islams wife, Husnara, 45, their older son, Sadiqul, 24, and daughter, Samira, 20, are being treated in hospital.
Samira remains in a critical condition in the intensive care unit while Husnara and Sadiqul are said to be recovering well.
Police are keen to speak to them as soon as they can to try to establish what happened.The family, from the Riverside area of Cardiff, were on a two-month holiday visiting relatives in the country and renting a flat in the eastern city of Sylhet.Supt Farid Uddin said: Our primary suspicion is they were poisoned.
When we reviewed the incident all the members of the family had slept in the same room, the doors were locked and there was no sign of forced entry or trauma with our prior experience, the case of poisoning made sense.We are doing everything necessary to determine the cause of their death.
Doctors are yet to send the postmortem report.
Our team has already preserved samples from the deceased persons, and we have also collected samples.
Theyll be further examined in our laboratory and well have a better understanding of the cause of their death.Our investigators are speaking with the relatives of the victims.
So far we dont think they have any enmity with anyone.
We are waiting for the remaining family members to get better so we can talk to them as well.Uddin said the family had slept in the same room after eating dinner on Monday night.
The following day, other relatives raised the alarm after they could hear no sound coming from the flat and tried unsuccessfully to open the door.Masudul Amin, the investigating officer, said: We are also speaking with the relatives who were in the apartment and other residents of the building.
No one has been detained or arrested in this murder.Dr Moiul Islam Dalim, who is in charge of the intensive care unit at the Sylhet MAG Osmani Medical College, said: We are treating three patients of the family for unknown poisoning.
The mother and the son are doing well now but the daughter, Samira, is critical.
Shes on life support.
The type of poisoning can only be determined after laboratory examinations of the samples we collected from the patients body.There was shock and disbelief in the Riverside area of Cardiff.
