New Delhi, Aug 30 (IANS): National Investigation Agency (NIA) on Wednesday said that it has conducted raids at multiple locations in Puducherry and Tamil Nadu regarding murder case of BJP leader Senthil Kumaran.

NIA said that the raids were conducted at premises of the key accused, including an undisclosed residential property of the main accused Niti alias Shri Nityanandam.
