Zee News today sent a defamation notice of 150 crore rupees to Naveen Jindal accusing his press conference on a sting operation as an attempt to divert attention from demand for independent probe in the coal blocks allocations controversy.

The sting operation was conducted by his company, Jindal Steel. Naveen Jindal had filed an extortion case against Zee News, accusing the channel of demanding bribe from him for not airing its story on the coalgate scam, in which Jindal's company had been named.
