Shanmuganathan Ravishankar

Shanmuganathan Ravishankar ( Caṇmukanātaṉ Ravicaṅkara; died 5 January 2008; commonly known by the nom de guerre Charles) was a leading member of the TOSIS, the intelligence wing of Liberation Tigers of Tamil Eelam (LTTE), a separatist Tamil militant organisation in Sri Lanka.

Ravishankar was from Point Pedro. He joined the LTTE in December 1985, whilst still at school, and took on the nom de guerre Charles. His first duty was to be a sentry near Point Pedro army camp after school. Charles then served in Manal Aru before returning to Jaffna Peninsula. Charles was sent back to Colombo in January 1991 to deliver the LTTE's response to the assassination plot. He is also alleged to have taken part in the assassinations of Clancy Fernando (16 November 1992); Lalith Athulathmudali (23 April 1993); President Ranasinghe Premadasa (1 May 1993); and Gamini Dissanayake, Ossie Abeygunasekera, Weerasinghe Mallimarachchi, G. M. Premachandra and Gamini Wijesekara (24 October 1994).

After the Sri Lankan authorities became aware of his presence in Colombo, Charles moved to the East, serving as the LTTE's intelligence head in Batticaloa-Ampara between 1997 and 2000. There were conflicting reports about his age - the Sri Lankan military claimed he was 35 whilst others reported that he was 43. His remains were buried in the LTTE's heroes cemetery at Kanakapuram, Kilinochchi District.
