Concerned over the killing of a Hindu activist in Karnataka, a delegation of BJP MPs today met Home Minister Rajnath Singh to seek a probe by the National Investigation Agency (NIA) into the case and other such violent deaths in the state. <br/><br/>BJP MP Shobha Karandlaje, who led the delegation, said Deepak Rao, hacked to death in the Dakshina Kannada district yesterday, was the 21st person to be killed in Karnataka in recent times.<br/><br/>She alleged the involvement of the radical Islamic outfit, the Popular Front of India (PFI), in most of the killings. She said, the organisation is active in Karnataka because the state government is supporting it. <br/><br/>The MPs' delegation requested the Union Home Minister to intervene in the matter. She said, it should be linked to national security issues. She accused the Congress-led Siddaramaiah government of trying to hush the cases up and of not disclosing the forensic report of another slain activist, Paresh Mesta. Mesta was killed in Uttara Kannada district's Honnavar town last month. She also charged the state government with supporting the Islamic group for vote bank politics.<br/><><>ANUPAM/2035 Hrs<br/>
