Two children have died while their parents are in a critical condition after the family ate leftover food at their home in Lahore’s Harbanspura area, police have said.

According to official details, Qadeer, his wife Asma and their two children ate curry that had been cooked the previous night. The family later developed severe symptoms and were taken to a hospital, where the two children died during treatment.

A crime scene unit and forensic experts visited the house and collected food samples and other evidence. A team from the food department also joined the investigation.

Police said that forensic experts suspected that a lizard may have contaminated the food, but they had not confirmed the cause of the deaths.

Samples collected from the house will undergo testing to determine what caused the food poisoning, officials said.
