The 'Q' branch police today arrested one of the two persons who came from Sri Lanka in a registered boat and jumped off their vessel and escaped after they saw the Coast Guard officials off Dhanushkodi near here.
Edmund (40) from Thalaimannar in Sri Lanka was arrested by the 'Q' branch police at Thangachimadam and was being questioned, they said.
Edmund and another person had jumped into the sea off Dhanushkodi yesterday after noticing the Coast Guard and Customs officials on a routine patrol in the area.
Their boat was later retrieved and a search had been launched to nab them.
