A 50-year-old Indian national who was languishing in a Pakistani jail for nearly 25 years on spying charges has died in Lahore under mysterious circumstances.
Kirpal Singh had allegedly crossed Wagah border into Pakistan in 1992 and was arrested. He was subsequently sentenced to death in a serial bomb blasts case in Pakistan's Punjab province.
"Kirpal Singh was found dead at his cell in early hours of Monday at Kot Lakhpat jail," an official of Kot Lakhpat jail said.
He said that the body of Kirpal has been shifted to the Jinah hospital Lahore for an autopsy.
A judicial magistrate was also called who recorded the statements of some prisoners about the death of Kirpal, the official said.
Asked if there were any signs of torture in Kirpal's death, he said, "The inmates of the jail near to Kirpal stated that he complained about pain in his chest and died instantly."
Kot Lakhpat jail police station head Nafees Ahmed said the jail authorities had called police to shift the body to the morgue.
"Apparently, it seems the Indian prisoner died of natural death. However, autopsy will tell the exact cause of death," he said.
Ill-fated Kirpal from Gurdaspur was reportedly acquitted of bomb blast charges by the Lahore high court but his death sentence could not be commuted because of unknown reasons.
Jagir Kaur, Kirpal's sister, earlier said that the family could not raise voice for his release due to financial constraints and no politician came forward to plead his case.
Earlier, in last week of April, 2013, Indian prisoner on death row Sarabjit Singh was brutally attacked and murdered by his fellow prisoners at Kot Lakhpat jail.
Both accused -- Muhammad Muddasar and Amir Tamba also condemned prisoners -- are facing trial for his murder in jail.
Sarabjit was arrested on charges of conducting four bomb blasts in Faisalabad, Multan and Lahore that killed 14 bystanders in 1990. He was sentenced to death.
