Karnataka Rakshana Vedike activists pulled down posters of the film and damaged several theatres in areas like Bidar, Hubli, Bagalkot, Raichur, Bijapur and other areas. Protestors are angry that Kannadigas are referred to dogs in a particular scene. There is a scene where villain Prakash Raj threatens Ajay that he would bring one thousand people from the Karnataka border to finish him. Ajay then said a lion is enough to thrash a thousand dogs.
However, the angry protestors claimed down after the distributors announced that the controversial dialogue has been removed from the film.
Ajay Devgn's much-hyped film Singham met a huge setback on the first day of its release after several Kannada organisations staged protests against the screening of the film in Karnataka over alleged derogatory remark on Kannadigas in the film. Its screening was halted in various parts of the state.
