"The continued imprisonment of our fishermen is causing considerable tension and ill will amongst fisherfolk in Tamil Nadu. Early decisive action by the Government of India is very essential and cannot be postponed indefinitely," she said in a letter to the Prime Minister.
Expressing shock over a Sri Lankan court extending remand of 35 fishermen of Ramanathapuram district till September 22, she also condemned the deportation of 21 fishermen of Nagapattinam district, who she said would have to further go through the harrowing process of deportation.
Reiterating that a case was fabricated against five fishermen, she said they were languishing in various jails in Sri Lanka since November 29 2011.
"I once again urge you to intervene personally and ensure that the matter is taken up in the most forceful diplomatic manner possible to ensure that the remaining Indian fishermen and their boats are released and a permanent solution is found to this long-simmering issue," she said.
"The Sri Lankan government has therefore made it very apparent that it is not ready to allow the Tamil Nadu fishermen to earn their livelihood by fishing in their traditional waters," Jayalalithaa said.
