In what is being seen as a setback for the Delhi Police, only one of the three men accused in the 2005 serial blasts case in Delhi -- in which more than 60 people died - has been convicted. But Lashkar-e-Taiba terrorist Tariq Ahmed Dar, accused of being the mastermind of the blasts, has been convicted only for belonging to the banned terror organisation. The charge carries a maximum sentence of 10-year jail term. He has already served 12 years in jail. The other two men have been acquitted outright.
