Lahore - Convicted Indian spy Sarabjit Singh succumbed to his injuries at Jinnah Hospital here on Wednesday night, reported private TV channels.

The head of medical board supervising Sarabjit’s treatment confirmed his death. Sarabjit Singh’s death occurred at 1 am, the head of the medical board said.

Sarabjit Singh, 49, received severe injuries when he was attacked by two other inmates at Kot Lakhpat Jail of Lahore on April 26 when he left his barracks for a stroll. He suffered severe injuries in the head. Singh was admitted to the Intensive Care Unit of the Jinnah Hospital where a medical board comprising senior neurosurgeons was treating him. He had been on ventilator life support since then.

The prisoners assaulted Sarabjit Singh with bricks and other blunt weapons and left him seriously injured.

Singh had illegally crossed into Pakistan on August 29, 1990. He was arrested on charges of carrying out four bombings in Faisalabad, Multan and Lahore and was later sentenced to death.

Singh’s security was tightened after the recent execution in India of Afzal Guru, who was convicted of involvement in the 2001 attack on the Indian parliament.

Singh’s mercy petitions were rejected by courts and former President Pervez Musharraf.

The outgoing PPP-led government put off Singh’s execution for an indefinite period in 2008.

Sarabjit Singh’s wife, sisters and two daughters left for India earlier on Wednesday after staying in Lahore for several days as Sarabjit’s conditin remained highly critical amid reports that he is brain dead.
