After attack on Mamata Banerjee's nephew and TMC MP Abhishek Banerjee in West Bengal's Sonarpur, an old video of Abhishek justifying attack on Union Minister and BJP leader JP Nadda in Diamond Harbour has surfaced online. "Nadda was in trouble in Diamond Harbour. What can I do about it? The outburst of people's anger isn't my responsibility," he had said.
