The makers of 'Zero' have responded to a complaint filed by Delhi MLA Manjinder Singh Sirsa, who said the film hurt Sikh sentiments by allegedly showing Shah Rukh Khan wearing 'Gatra Kirpan'. "The film doesn't depict a Kirpan but...has used what's commonly known as a Katar," the makers said. "Any concern this may have caused is completely inadvertent," they added.
