Over 300 Indians who were about to head to Katchatheevu from Rameshwaram to stage a protest against the Sri Lankan government were arrested by the Indian police.
Indian media reports said that around 350 supporters of a Tamil outfit known as the Makkal Viduthalai Katchi were arrested when they were boarding boats to reach the island which is owned by Sri Lanka.
The group, led by party founder and former legislator Murugavel Rajan, had staged a rally against the Sri Lankan government and were then preparing to head to the Katchatheevu Island.
Outlook India reported that the activists earlier burnt an effigy of President Mahinda Rajapakse in protest against alleged attacks on Indian fishermen by the Sri Lankan navy.
They alleged that over 550 fishermen had been killed over time and the only solution was to retrieve Katchatheevu.
Murugavelrajan condemned Minister Douglas Devanandha for his threat to mobilise Sri Lankan fisherman and hold a rally in mid sea off the Rameswaram coast and for charging that Indian fishermen were violating the international maritime boundary line.
