The 22-year-old Indian fisherman, Bridgo, was shot dead on Monday allegedly by Lankan Navy personnel while he was fishing in a mechanised boat at a short distance off Katchatheevu islet.
The Sri Lankan government had yesterday said an initial probe report has ruled out its navy's involvement in the killing of the fisherman.
Hardening their stand, the protesters today demanded that External Affairs Minister Sushma Swaraj visit them and assure that they would not be attacked by Sri Lankan naval men while fishing in their traditional areas in the Palk Strait.
A large number of police personnel have been posted on the island to monitor the situation which was tense but under control, police said.
Tamil Nadu Chief Minister Edappadi K Palaniswami had yesterday shot off a letter to the Centre, saying the Sri Lankan High Commissioner to India should be summoned forthwith and "the strong feelings" of the state and central governments about the "unprovoked" firing on fishermen be conveyed.
