The demonstration, which followed Friday prayers at the Taqwayatul Iman mosque on Nadan Mahal Road, saw protesters chanting slogans demanding that "objectionable portions be deleted" and that the trilingual film be "banned from release in Uttar Pradesh".
Meanwhile, there was strong police deployment at theatres and malls where the film opened today although its morning screening could not go through due to a delay in the arrival of prints, sources said.
But its noon show went ahead as planned and there were no untoward incidents during the protest and at the cinema halls, they said.
Senior Samajwadi Party leader Ram Asrey Kushwaha had yesterday said that Haasan's film could be banned in Uttar Pradesh if it was found that it "hurt the sentiments" of Muslims and indulges in "character assassination".
