THIRUVANANTHAPURAM: The NIA reaching the Secretariat is an insult to Kerala, said opposition leader Ramesh Chennithala. Unusual acts are happening in the state now. This has never happened in any other states in India. The chief minister is behaving as if nothing has happened. The chief minister is challenging the people. He should resign and go politely. The police has so far not taken any steps in the gold smuggling case and this is with the consent of the chief minister. The home department has been protecting the accused from the very beginning, said Chennithala.
