The mortal remains of Kirpal Singh, the Indian prisoner who died under mysterious circumstances in Lahore’s Kot Lakhpat Jail, will be handed over to India on Tuesday, said sources.

Kirpal’s family members had on Friday met Union home minister Rajnath Singh to express their concerns over the gruesome treatment meted out to the Indians languishing in Pakistan jails.

The home minister assured them that efforts would be made to bring back Kirpal’s body from Pakistan. External affairs minister Sushma Swaraj on Wednesday assured Kirpal’s kin that India would get his body back home.

Kirpal’s family had earlier rejected Pakistan ’s claim that he died of a heart attack and demanded a post-mortem to ascertain the reasons behind his death. “How can we believe that he died of a heart attack? His body should be handed over to us and post-mortem be done. We want to know the truth,” Singh’s nephew had told ANI.
