Thirty-six years after they hijacked an Indian Airlines Boeing-737 to Lahore, their arrest and imprisonment in Pakistan, two of the five Dal Khalsa hijackers are being tried for sedition.

They hijacked Flight IC-423 on September 29, 1981, after it took off from Delhi for Srinagar via Amritsar and made the pilot land at Lahore. Their demand was the release of then Damdami Taksal head Sant Jarnail Singh Bhindranwale, who was arrested nine days before in connection with murder of a Hindi daily editor.
