Nitesh, the younger son of slain BSP leader Deepak Bhardwaj (in pic), conspired to eliminate his father six months ago, police said on Tuesday. Nitesh hatched the conspiracy after his father threatened to prevent him from entering the south Delhi farmhouse following a dispute between them. Deepak Bhardwaj was shot dead in his farmhouse. “The exact reason behind the killing is yet to come out. But Nitesh was stressed over the threat by his father,” said a police officer.
