Lahore:
Police today registered a case of attempted murder against two prisoners for brutally assaulting Indian national Sarabjit Singh, who was in a "deep coma" in a hospital in Lahore.
Official sources told PTI that the FIR against prisoners Amer Aftab and Mudassar was registered following a complaint from Assistant Superintendent Ishtiaq Ahmed Gill of Kot Lakhpath Jail.
The two men were booked under sections 324 (attempted murder) and 334 (causing severe injuries) of the Pakistan Penal Code.
Quoting the FIR, a police official said the two prisoners attacked Sarabjit after opening the gate of his barrack in one of the most secure sections of the jail.
The official said another two prisoners, Ehsanul Haq and Muhammad Safdar, had claimed that they had come to save Sarabjit from the attackers.
Aftab and Mudassar are death row prisoners and have been held at Kot Lakhpat Jail since 2009 and 2005, respectively.
However, sources told PTI that at least six prisoners were involved in the attack on 49-year-old Sarabjit.
The identities of the other prisoners could not immediately be ascertained.
Aftab was sentenced to death after being convicted of murder. He was involved in robberies and other serious crimes.
In a separate development, an inquiry committee headed by Deputy Inspector General of Police Malik Mubashir interrogated all six accused.
The six prisoners are being held in a special barrack under high security, sources said.
According to the sources, Mubashir will submit his report to provincial and federal authorities later today.
There has been no official word from the jail's administration or the caretaker Punjab government on the incident or Sarabjit's condition.
Doctors at the state-run Jinnah Hospital, where Sarabjit was admitted yesterday, have refused to speak to the media.
Official sources told PTI that Sarabjit was in a "deep coma" and had been put on a ventilator.
Doctors were unable to perform surgery on him yesterday because of extensive internal bleeding caused by a severe head injury.
"No surgery can be performed till his condition stabilises," a source said.
Two officials of the Indian High Commission got consular access to Sarabjit Singh in the ICU of Jinnah Hospital at about 2 am.
The Indian mission had contacted Pakistan's Foreign Office last night to seek consular access.
Sarabjit was convicted of alleged involvement in a string of bomb attacks in Punjab province that killed 14 people in 1990.
His mercy petitions were rejected by the courts and former President Pervez Musharraf.
The outgoing Pakistan People's Party-led government put off Sarabjit's execution for an indefinite period in 2008.
Sarabjit's family says he is the victim of mistaken identity and had strayed across the border in an inebriated state.
