He has been named by police as 22-year-old Darren O'Neill.
Mr O'Neill was admitted to hospital following an incident at Tyrella Beach in Downpatrick on Thursday.
Detective Chief Inspector Darren McCartney said: "I would like to offer my sympathy to the family and friends of Darren at this very sad time."
He appealed for witnesses, or anyone with information, to contact detectives.
A post-mortem examination will be carried out to determine the cause of death.
