Ajmal Qasab, the sole surviving Pakistani terrorist involved in the 26/11 attacks on Mumbai, has been suffering from high fever - earlier suspected to be dengue - for the last four days, a prison official said.
A team of doctors from Mumbai's JJ Hospital is treating him in the Arthur Road prison, where he has been lodged since his conviction.
Confirming the reports, JJ Hospital dean TP Lahane said that while the symptoms of the fever were "dengue-like", the possibility of the disease has been nearly ruled out.
"Doctors are monitoring Kasab's health and he was subjected to various tests, most of which have been negative for dengue. We are expecting results of one more medical test," Lahane said.
A jail official, however, said that Qasab would not be shifted to the hospital and he would be attended to by doctors within the jail premises.
Qasab is one of the 10 Pakistani terrorists who sailed from their country and illegally sneaked into Mumbai on the night of Nov 26, 2008, for a terror siege of the city that ended Nov 29 afternoon.
The mayhem that Qasab and his nine accomplices unleashed on the city claimed 166 lives.
