Actor Salman Khan has urged the people of Pakistan to help free Sarabjit Singh, an Indian who has been on death row in a Lahore jail since 1990. Sarabjit's family rejoiced when reports emerged on June 27, 2012 that he was to be freed, only to despair when Pakistan clarified it was another Indian prisoner, Surjeet Singh, who was being released, not Sarabjit. In a series of tweets, Salman has appealed for Sarabjit's freedom:

"It would be the most amazing gesture, to send surabjeet back to his family after 30 years. Hope u support me like its your own cause," he said in one of his tweets.
