30 fishermen from Rameswaram were arrested and their five mechanised boats seized by the Navy personnel while fishing near Katchatheevu, an islet ceded by India to the neighbouring country, around 5 PM today, they said.
Official sources said the arrested fishermen were taken to Talaimannar by the Navy.
They had last night arrested 26 fishermen, who ventured into the sea in six mechanised vessels from Karaikal, South-East off Kodiakarai coast and took them to Kangesanthurai port in Sri Lanka, the sources said.
They were handed over to the police in the islet of Kayts for further action, he said.
Representatives of Fishermen Associations in Rameswaram and Karaikal convened an emergency meeting and urged the authorities to take urgent steps to secure the release of all the Tamil fishermen detained in Sri Lanka.
Sri Lankan Navy had last month arrested 53 Indian fishermen. On March 15, 34 of them were released after India summoned Sri Lanka's Deputy High Commissioner and lodged a strong protest over the issue.
