New Delhi, Mar 18 : Sarabjit Singh's sister on Tuesday made an appeal at the Pakistan High Commission for securing his release.

Dalbir Kaur, sister of Sarabjit Singh submitted an appeal to the Pakistan High Commission in India appealing for the release of her brother as soon as possible.

"I and my family should be given permission to meet Sarabjit. I requested them not to treat my brother harshly and he should be forgiven, as he is innocent. I have submitted all the documents, which claim that he is Sarabjit. I have requested them to convey this message to President Pervez Musharraf that my brother be treated in a civil manner and should be given forgiveness," said Dalbir Kaur.

Dalbir Kaur recently failed to gain clemency following the rejection of his mercy plea by President Musharraf.

Sarabjit Singh, the Indian convicted of spying in Pakistan is to be hanged on April 1 following President Musharraf's rejection of his mercy plea, a senior prison officer in Lahore said on Sunday.

Singh was sentenced to death in 1991 for spying and carrying out four bomb blasts that killed 14 people.

According to the Superintendent of the Lahore's Kot Lakhpat prison, Javed Latif, President Musharraf turned down Singh's petition for clemency on March 4.

Singh's family has said he accidentally crossed into Pakistan in 1990 while he was drunk.

Pakistani officials say Singh was arrested while trying to slip back into India after the bomb blasts.

On March 4, Musharraf accepted a mercy plea and ordered the release of another Indian, Kashmir Singh, who spent 35 years on death row in Pakistan for spying charges.

Pakistan said the release was made on humanitarian grounds.

Human rights activist and caretaker Minister Ansar Burney who propelled the release of Kashmir Singh, told reporters in Islamabad on Monday that he had no intention of helping Sarabjit Singh.

The Indian Government meanwhile has appealed to the Pakistan Government to grant clemency to Sarabjit Singh on humanitarian grounds. (ANI)
