A fishing vessel manned by the suspects was seized by the Sri Lanka Navy on the high seas about 900 nautical miles (1,600 km) south of Colombo last week.
The ship was carrying 250 kg of heroin and was brought ashore by the navy to the port of Colombo on Wednesday where the suspected smugglers were handed over to police.
