The assurance was given when Home Secretary R K Singh called on Pakistan Interior Minister Rehman Malik in Islamabad last week.
"I have requested the Pakistan Interior Minister and my counterpart (Interior Secretary Khwaja Siddique Akbar) to release Sarabjit Singh. They have assured me that they would consider our request positively," Singh told reporters here today.
Singh was briefing about his visit to Islamabad for the Indo-Pak Home Secretary-level talks on May 24 and 25.
During the talks, the Indian delegation had cited the release of Pakistani virologist Khalil Chishti and requested Islamabad to release Sarabjit as well.
Sarabjit was convicted for his involvement in 1990 serial bomb blasts in Lahore and Multan that killed 14 people. He was given death sentence, but his execution was indefinitely put off by the Pakistan government.
He is currently lodged in Kot Lakhpat Jail in Lahore.
Earlier, the Pakistan Interior Secretary had said that the Indian team raised the issue of Sarabjit and the matter would be decided in line with Pakistani laws.
