These forces should fight the parties politically and not resort to such tactics, to muzzle the voice of opposition, he told reporters here.
Recalling BJP President Amit Shah's reported statement that it was CPI(M) which was the main opponent of his party, Rangarajan said it was not not fair to indulge in such action, which would affect the development of the Nation.
There was lack of security in the city due to inadequate number of personnel in the police department, which has to be strengthened, he said.
It was a question mark whether Tamil Nadu government is functioning or not, he said.
On GST, Rangarajan said that people will suffer due to additional tax and there was every possibility of price increase for essential commodities after its rollout.
