Bharatiya Janata Party President Amit Shah on Saturday reached Kolkata and addressed a rally. Before he reached the rally venue, the BJP leader was shown black flags by youth Congress workers. The youth Congress workers raised slogans against Mr Shah and Prime Minister Narendra Modi. They also tried to block his convoy by putting their bikes in the way. The police, however, got the way cleared for Amit Shah's convoy. Amit Shah was welcomed in the state by BJP state in-charge Kailash Vijaywargiya and Dilip Ghosh.
