The body of the 18-year-old Briton who has not been seen since he went for a swim off Bota beach in Huelva on Sunday afternoon was discovered on Tuesday morning at a beach four miles away by two Civil Protection volunteers working with the search parties which had been searching for the youth since he disappeared. There will be an autopsy, but a Guardia Civil spokesman said it was believed to be death by drowning. The sea off Bota beach is known for its treacherous currents and several people have drowned there in recent years.
