According to reports, a lizard fell into the food prepared for women prisoners at Kot Lakhpat Jail yesterday. Authorities stopped serving the food when the condition of some women deteriorated.
They were taken to a nearby hospital, where doctors said they were now out of danger.
Deputy Inspector General of Police (Prisons) Malik Mubashar said a departmental inquiry had been launched and a report would be submitted within 24 hours.
"The incident apparently happened when food was being distributed among women prisoners. A lizard had fallen into one of three cauldrons of chicken curry. All the cauldrons were disposed of," he said.
