The scurrilous remarks of MDMK leader Vaiko against the High Commissioner of Sri Lanka Mr Prasad Kariyawasam is an offence under Sections 124A and 125 of the Indian Penal Code. The Tamil Nadu Police must immediately register suo moto a FIR against Mr. Vaiko,
arrest him for custodial interrogation, and launch his prosecution. Otherwise the Crime Branch in the Home Ministry should register the FIR.
What the Sri Lanka High Commissioner said about India's connection with Sri Lankan people is absolutely correct and proved by recent studies on DNA of South Asians and published in learned journals.
