Prior to his disappearance, Raveendranath was attending the annual sessions of the Sri Lanka Association for the Advancement of Science at Vidya Mandiraya, which is situated in a high security zone in Colombo. He was last seen leaving the session after receiving a phone call.
Local media have reported that there are allegations that gunmen belonging to the paramilitary organisation Tamil Makkal Viduthalia Pulikal (TMVP) have kidnapped him.

Robert J. Quinn Director Scholars at Risk Network issued an appeal to president Mahinda Rajapakse
 ;templatestyles src="Template:Blockquote/styles.css" / ;"We are greatly concerned about his physical well being, not least because in September of this year unidentified gunmen demanding Prof. Raveendranath's resignation kidnapped the Dean of the Faculty of Arts at Eastern University, Professor Bala Sugumar, and because in the months thereafter Professor Raveendranath received repeated death threats demanding he abandon his post".
The staff of the Eastern University of Sri Lanka went on strike demanding his release.
Government investigation.
The Criminal Investigation Department (CID) investigation revealed that the initial threats to him came from an armed group suspected to be the TMVP. Raveendranath's driver has been detained and it is alleged that he had received telephone calls from people "believed to be" members of the TMVP. His kidnapping is seen as part of series of abductions of Tamils and are part of the "era of terror" abductions by death squads and pro government militias which were responsible for the disappearances of thousands of people since the 1980s. Human rights watch states majority of disappearances involve Sri Lankan security forces and paramilitary groups like the TMVP led by Karuna and the government response has been inadequate.
