A group of fans gathered at the actor's fans association office in Chennai on Sunday and allegedly shouted slogans against Thenappan and Bala.
Even in Coimbatore, Madurai and Erode they reportedly held protests seeking apologies from Thenappan and Bala.
It may be recalled that Ajith was assigned to act in Naan Kadavul.
However at the last moment, the actor pulled out of the project and Bala announced that Arya would act instead of Ajith.
Both Ajith and Bala said that they decided to part after mutual discussions.
However the vernacular media has been carrying reports that Ajith was indeed threatened for pulling out of the movie.
When Ajith was contacted, the actor maintained that he was not threatened and it was his personal decision to reject the offer.
