Leader of the Opposition V.S. Achuthanandan has urged the government to refer the case relating to the Popular Front of India (PFI)-run training camp to the National Investigation Agency (NIA).

In a statement here on Wednesday, Mr. Achuthanandan said those arrested from the PFI-run camp at Narath in Kannur should be subjected to detailed questioning and those who had escaped from the camp should be arrested. The fact that a training camp could operate in a densely populated area such as Narath showed how widespread and strong the activities of religious extremists were, he said.
