Tamil Nadu Chief Minister J. Jayalalithaa today sought Prime Minister Manmohan Singh’s intervention to secure the immediate release of 80 fishermen detained illegally by the Sri Lankan Navy.

She expressed distress over the recent arrest of 20 fishermen and seizure of five mechanised boats on November 21, World Fisheries Day, while they were fishing in their traditional waters of Palk Bay.

In a letter to Singh, she insisted that India use the highest diplomatic channels to secure the release of 80 fishermen and 47 fishing boats detained by the Sri Lankan authorities at the earliest.
