Chennai,  Four Tamil Nadu fishermen were arrested 
 by the Sri Lankan Navy personnel for fishing in the Lankan waters 
 early on Sunday morning. Reports received here said the fishermen, who ventured into
 the sea yesterday in a mechanised, were arrested on charges
 of crossing the International Maritime Boundary Line in
 the high seas. The arrested fishermen were identified as boat owner Constan 
 (42), K Ramesh (34), Pandu (50)–all from Kottaipattinam coastal 
 village–and N Mohan of Pamban near Rameswaram. The arrested fishermen were taken to the Kankesanthurai naval 
 base for further inquiry. The arrest of four fishermen comes close on the heels of  arrest of 36 fishermen last week by the Lankan Navy, which 
 was condemned by various political parties, who urged the
 Centre to take steps to secure their release.
