NEW DELHI, July 20 (Xinhua) -- Some 78 female inmates of a jail in India's financial capital have been hospitalised due to suspected food poisoning Friday, sources said.

The prisoners of Byculla jail were rushed to the state-run J.J. Hospital when they complained of stomach pain, nausea, vomitting and diarrhea a few hours after having their breakfast in the morning, sources said.

The hospital has confirmed the admission of the prisoners. "Seventy-eight patients have so far been admitted to the hospital. A few more are likely be brought to the hospital. However, none is in serious condition," hospital dean Mukund Tayade told the media.

A high-level probe has been ordered into the incident, sources added.

This is the second such incident in the past three months. Two prisoners died and over 50 had to be hospitalised for diarrhea due to suspected food or water poisoning in central Indian state of Chhattisgarh in May.
