Man swallows 220 diamonds in smuggling attempt Capt. Paul Ramaloko of the South African Police Service said investigators arrested the man on Tuesday night as he waited in line at security at O.R. Tambo International Airport just outside of Johannesburg. Ramaloko said a scan of the man's body showed the diamonds, which later were recovered. He said the man had been on his way to Dubai. Ramaloko said the diamonds are worth about £1.5 million. Authorities believe the man belongs to a smuggling ring, as another man was arrested in March attempting the same thing. South Africa is one of the world's top diamond producers.
