Dalbir Kaur, sister of Sarabjit, along with his wife and daughters participated in last evening's march."Dalbir Kaur has been pleading with Pakistan President Pervez Musharraf and has been pursuing the issue with Prime Minister Dr. Manmohan Singh. Looking at her struggle, we thought of joining her in her painstaking efforts to secure the release of her brother," said Sandeep Saini, an activist.
Pakistan's human rights activist Ansar Burney has rekindled hopes of Sarabjit's release as he said that Sarabjit could have been "a victim of mistaken identity".
Last month, Burney had urged the new Pakistani Government to consider converting Sarabjit's death sentence into life imprisonment on humanitarian grounds as he had spent more time than a life sentence on death row in Pakistani jails.
President Pervez Musharraf had earlier rejected his appeal for clemency.
Burney had played a significant role in the release of another Indian Kashmir Singh, after spending 35 years in Pakistani jails.
The day Kashmir Singh was released, Sarbjit's sister Dalbir Kaur had requested Burney to take up the case of her brother. Sarabjit's family claims that his was a clear case of mistaken identity.
