An Indian national, Kirpal Singh, 50, who was languishing at Lahore’s Kot Lakhpat Jail for more than 20 years on spying charges died mysteriously on April 11.
Singh was arrested for allegedly crossing Wagah border into Pakistan in 1992.
He was subsequently sentenced to death in a serial bomb blasts case in Pakistan’s Punjab province.
Singh, who hailed from Gurdaspur in Punjab, has reportedly been acquitted of bomb blast charges by the Lahore High Court but his death sentence could not be commuted because of unknown reasons.
On whether Singh died of torture, an official of Kot Lakhpat Jail said, the inmates of the jail near to Kirpal stated that he complained about pain in his chest and died instantly.
The official said it seems the Indian prisoner died of natural death, and autopsy will tell the exact cause of death.
Jagir Kaur, Kirpal’s sister, earlier said that no politician came forward to plead his case, and his family couldn’t raise voice for his release due to financial constraints.
His kin say the least the government can now do is to get back his body for the last rites.
The last time the family heard of him was in early March this year, when they received two letters from Kripal written in Urdu.
While in prison in April 2013, he was was brutally attacked by his fellow prisoners at Kot Lakhpat Jail. He died six days later at Jinnah Hospital, Lahore.
Both accused – Muhammad Muddasar and Amir Tamba also condemned prisoners – are facing trial of his murder at the 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.
