Clashes broke out between BJP supporters and student activists those of the Left and Trinamool Congress during Amit Shah's roadshow in the city on Tuesday, news agency PTI reported quoting officials.

Trouble began after stones were pelted at Amit Shah's convoy as it passed through College Street and the arterial Bidhan Sarani on its way to Swami Vivekananda's residence in north Kolkata, a little over 3.5 km from Esplanade in the heart of the city, where it began.
