Dara Singh (Raja Azaad Singh), who etched the four letter word ‘MARD’ on the chest of his son Raju (Amitabh Bachchan) in the Manmohan Desai-directed film <em>Mard</em> is no more. The Rustam-e-Hind, who never lost a fight in the ring, sadly, breathed his last early this morning (12 July 2012). He died at his house where he was shifted from the Kokilaben Dhirubhai Ambani Hospital. The wrestler-turned actor had been undergoing dialysis at the hospital. “Angel now gone to shine like a star up above,” the actor’s son, Vindu Dara Singh texted after his father's death.
