A fisherman from Karaikal was injured when he was fired upon allegedly by the Sri Lankan Navy, about 11 nautical miles off the Kodiakarai coast, early on Thursday.
Shenbagam (40) of Kilinjamedu was shot in the back while steering one of two mechanised boats in which a group of fishermen ventured into the sea last Saturday. A few others escaped, the fishermen said in a police complaint later.
Chief Minister Jayalalithaa voiced serious concern over such incidents and demanded that the Union government take firm action.
In a letter to the Prime Minister, she said the latest incident was an attempt to intimidate India and “browbeat” it into not raising its voice against Sri Lankan authorities in international forums.
The incident should be viewed in the backdrop of protests by MPs from Tamil Nadu against atrocities perpetrated on Tamils in Sri Lanka.
