Indian prisoner Sarabjit Singh, who is on death row in a Pakistani jail, appears to be a case of mistaken identity, former Pakistani minister and United Nations Human Rights Council advisory committee member Ansar Burney said in Chandigarh on Friday.

"Prima facie his (Sarabjit's) case appears to be that of mistaken identity," he told reporters after holding confabulations with the Punjab State Human Rights Commission chairperson and it's other members.

After collecting evidence in the shape of a video CD and copy of an FIR from the family members of Sarabjit, Burney said, "Prima facie it appears to be a case of mistaken identity.

"But, it will take some time to establish this. I will have to deeply look into the evidence provided by Sarabjit's family members to me," he said.

Burney had on Thursday said that he would soon take up the issue of Sarabjit's release with the newly formed government in Pakistan.

He said that during the trial in Sarabjit's case in Pakistan, the witnesses had deposed before the court and identified him as the prime suspect in serial bomb blasts case.

"Now I will have to first see his case and then only I can proceed in favour of Sarabjit by keeping in mind the human rights aspects," he said. Burney said that if an iota of doubt comes in a case of death penalty, the award must be commuted.

Sarabjit, who is lodged in a Lahore [Images] jail, was sentenced to death for his alleged involvement in the 1990 serial blasts in Lahore and Multan.
