Eight Tamil Nadu fishermen were arrested by the Sri Lankan navy on Sunday for allegedly crossing the maritime boundary.
The men were arrested off the coast of Neduntheevu.
"The fishermen from Akarapettai in Nagapattinam district, who put out to sea in a mechanised boat, were arrested on charges of poaching fish in Lanka’s territorial waters," the Assistant Director of Fisheries Department, Nagapattinam Gangadhar was quoted by PTI as saying.
This is the latest in the ongoing arrests of Tamil Nadu fishermen by Sri Lankan navy personnel. Last month the chief minister of Tamil Nadu sent another letter to the Indian premier, urging him to intervene and secure the release of dozens of detained fishermen.
