It looks like NTR fans are trying their best to make everyone believe that NTR is not playing a dual role in 'Dammu' and he is also not playing any Police Officer role in the movie. But, they are the ones who originally leaked these details.
If we go into the details, in 'Dammu', NTR is playing a dual role, one as a faction leader and the other one as a cop. The makers initially wanted to keep this information confidential until the release of the film. But, NTR fans were too hasty in revealing these details. In open forums, they discussed about these details without having any idea that the information will be leaked to everyone. Now, after realizing their mistake, they are repeatedly saying that NTR is not playing any dual role in the film and NTR will not be seen in police getup. But their efforts are getting wasted as no one is ready to believe what they are trying to say now.
