Bollywood superstar Salman Khan who is well known for his charity works, has showed his humane face once more by joining the chorus for the release of Indian national Sarabjit Singh, who is in Pakistan prison on a death row. An initiative was launched on social networking site Facebook to gather signs for a petition seeking the release of Sarabjit. It is planned that the petition will be handed over to the Pakistan government. Calling for Sarabjits release, Salman wrote on his wall, "For over 20 years, Sarabjit Singh is in a Pakistan prison for a crime he did not commit. He and his family have suffered for too long. Please sign this petition to appeal to the Pakistan government that he be freed and united with his family in Punjab." He had earlier also tweeted in Sarabjits support, saying, "Wanted to tweet this for the longest time, saw a pic of surabjeets sister, it Killed me. Felt real sad for her. Help me help her. It would be the most amazing waku doki gesture, to send surabjeet back to his family after 30 years. Hope u support me like its your own cause ...B a part of 1 family's happiness. (sic)". According to reports, Sarabjits sister and daughters met Salman on the sets of Dabangg 2 seeking his support.
