The Coast Guard personnel first spotted a Sri Lankan boat with six fishermen on board during routine surveillance in Bay of Bengal on Friday.
After verification, they seized the boat and handed it over to Kakinada Marine police, along with the apprehended fishermen and over 500 kg of tuna last evening, a Marine police official said.
The Sri Lankan fishermen were booked under various sections of the Maritime Zones of India Act and were produced before a court for judicial remand, the official said, adding that the fishermen had intentionally entered Indian waters and "illegally" carried out fishing activity.
