A police constable from Kokkadicholai, who was reported missing in 2008, is believed to have been murdered and buried, the force's spokesperson said today.
The discovery was made during a CID investigation into last year's police checkpoint killing at Vavuniyathivu by Islamist extremists.
Three suspects have been arrested by the CID over the constable's murder, who is understood to have been shot dead on July 27, 2008.
Excavation work is taking place at the site at which he is believed to have been buried.
