State BJP president K Annamalai on Thursday said the Tamil soil has become a haven for all anti-national elements to take refuge. Annamalai said, “We are happy that the case is going to National Investigation Agency (NIA). The tentacles of this terror are much deeper. It has spread across Coimbatore.”“We are worried about the mindset of this government. The case was of such seriousness and ramifications but the state government denied admitting it and even forced the DGP to call it a cylinder blast… Such kind of thing never happened in the history of Tamil Nadu. We have never seen this kind of incompetent government, ” the state BJP leader said.
