"We express great anguish at the demise of Shri Sarabjit Singh who succumbed to injuries after the brutal attack on him in Kot Lakhpat jail. This was, put simply, the killing of our citizen while in the custody of Pakistan jail authorities," the Ministry of External Affairs (MEA) said in a statement on Thursday.
Demanding punishment for culprits, the Ministry said: "We demand that the Government of Pakistan conducts a thorough investigation to identify those who were responsible, and ensure that they are punished."
"We share the pain and sorrow of Sarabjit Singh's family. We have asked the Pakistani authorities to release the body of Sarabjit Singh so that he can be given a funeral in India and among his own people," it said.
"The shocking attack on Shri Sarabjit Singh highlights the need for concerted action by Pakistan to safeguard Indians in Pakistani jails," the Ministry said.
Sarabjit was reportedly attacked by two other inmates Rizwan and Amir- both death row prisoners- at the Kot Lakhpat Jail, Lahore on Friday last (April 26). He received serious head injuries and was on ventilator, till he succumbed early on Thursday in Lahore's Jinnah Hospital.
Pakistan said Sarabjit Singh died of cardiac arrest.
Sarabjit's family on Wednesday returned to India via Wagah border after meeting him in a Lahore hospital and slammed Pakistan for its treatment of the Indian prisoner.
Sarabjit has been languishing in Pakistani jail for over 20 years after a Pakistani anti-terrorist court awarded him the death sentence in 1991.
He had been convicted of involvement in a string of bombings in Punjab in 1990 that killed 14 people.
