Calling BJP President Amit Shah a "liar and cheater", the Trinamool Congress (TMC) on Wednesday accused the BJP of vandalizing Bengali polymath Ishwar Chandra Vidyasagar's statue during clashes at his roadshow in Kolkata on Tuesday."BJP people indulged in the violence during Amit Shah's roadshow. Roadshow is just a roadshow, you are not supposed to paste posters on government buildings and other places," TMC MP Derek O'Brien told the media here.O'Brien showed two videos in which people were seen vandalizing public property. The TMC leader claimed he had 44 more such videos which he said can prove that "BJP goons" were involved in the violence in Kolkata."These videos establish that the BJP President is a liar and cheater."Another TMC leader, Manish Gupta, accused the BJP of bringing "goons" and keeping them in hotels to indulge in violence.O'Brien also accused the central forces of helping the Bharatiya Janata Party (BJP) in West Bengal."The Central forces are in league with the BJP in Bengal. They are in alliance with the BJP."O'Brien said he along with a TMC delegation will meet the Election Commission and lodge a complaint regarding the violence, and also hand over the videos which he said were "authentic proof" against the BJP.
