BJP leader Swapan Dasgupta alleged the police acted in an extreme manner without any provocation by BJP workers and leaders, who took out a protest in Kolkata against the Mamata Banerjee government today. "Ours was a high-spirited, but peaceful demonstration…This is a very sad day for democracy. I could have been hurt. It could have been much worse," he said. Several BJP leaders, including Leader of the Opposition Suvendu Adhikari, were detained by the Kolkata Police today when they were marching to state secretariat 'Nabanna' in Kolkata, as part of a huge protest over alleged corruption by the ruling Trinamool Congress government.
