The National Investigation Agency (NIA) officials on Thursday carried out raids at multiple locations, including residences of second-rung leaders of the banned Islamist outfit Popular Front of India in Kerala.
The raids, which started late last night are still underway, sources in the Kerala police said.

Officials then had described the mega crackdown as the "largest-ever investigation process till date" against the PFI.
