Thirteen Tamil Nadu fishermen were arrested on Sunday morning by the Sri Lankan navy for allegedly entering island's eaters.
The navy also confiscated two fishing trawlers, which have been taken to the naval base at Karainagar.
The 13 fishermen have been handed over to Jaffna fisheries officials, the Daily Mirror reported.
The arrest comes just days after courts in the North-East ordered the release of 69 Indian fishermen detained in Sri Lanka.
