police investigation is underway after a father and son from Cardiff were poisoned.

It was reported that Rafiqul Islam and his son Mahiqul died while his wife Hosne and other two children, Samira and Sadikul, are still in hospital.

The family had been staying in a flat near Sylhet, Bangladesh.

They had been on a two-month trip to the country.

Police say that after dinner on July 25, 2022, the entire family fell asleep in the same room. Between 10 am and 10:30 am the next day, their relatives tried to open the door.

They became concerned when they heard no sounds and called the police.

Police found the door locked from the inside, broke it open and found all five family members unconscious.

Police said the family were poisoned and while they were baffled at how this could happen, investigators found “light blue and brown liquids” in the noses of the father and son during an autopsy.

DSP Uddin said: “After discussing the overall situation with the doctors and inspecting the scene we believe this may have been a case of poisoning.

“The investigation is ongoing into whether it is poisoning or something else.”
