Shantanu Mukherjee, grandson of Bengali fighter Gopal Mukherjee, filed FIR against filmmaker Vivek Agnihotri for allegedly distorting his grandfather's identity in 'The Bengal Files'. Shantanu points out that the film introduces Gopal as 'Ek Tha Kashai Gopal Patha' which is inaccurate as Gopal was wrestler and key figure in 1946 riots. For context, 'Kashai' means butcher and 'Patha' means goat.
