The smashing of a statue of Ishwar Chandra Vidyasagar in clashes during BJP president Amit Shah's roadshow in Kolkata on Tuesday has set off a whodunit where video clips are flying from both sides, the BJP and Chief Minister Mamata Banerjee's Trinamool Congress. Amit Shah said Trinamool activists attacked his roadshow and it was Mamata Banerjee who had the Vidyasagar bust broken as part of a "conspiracy" to blame the BJP ahead of the last round of voting for the national election. Trinamool leader Derek O'Brien lobbed the allegation right back and called the BJP chief "Dhokabaaz" and "pukeworthy". He also complained to the Election Commission, submitted what he called video proof that the BJP was behind the vandalism.
