The Delhi Police today arrested Nitesh, the younger son of BSP leader Deepak Bhardwaj, and has accused him of being the mastermind to murder his father at his sprawling farmhouse - called Nitesh Kunj - in south Delhi last month. Mr Bhardwaj's lawyer, Baljeet, who was privy to details of his land deals, has also been arrested in what the police now call a "web of conspiracies" to kill the real estate tycoon.
