The Sri Lankan Navy on Thursday said it arrested 16 Indian fishermen for illegal poaching in the island-country's territorial waters. Navy spokesman Akram Alavi told Xinhua news agency that the navy assisted the Coast Guard in arresting the fishermen at two separate locations. He said the fishermen were arrested south of Delft islands and off Mannar. The navy spokesman said that three boats used by the Indians were also seized. Akram Alavi said the latest arrests follow the arrest of 17 Indian fishermen two days earlier.
