At a time when Punjab has seen 11 encounters in two weeks, the ghost of an alleged forced disappearance and murder of an acting Akal Takht jathedar has come back to haunt the state police over 30 years later. Acting Akal Takht jathedar Gurdev Singh Kaunke had been taken in custody in December 1992, at the height of militancy in the state, and the police had said he had escaped from their custody a few days later.
