Crime in South African cities has dropped considerably during the football World Cup, dpa quoted the South African daily Beeld as reporting today. It said the number of reported crimes had fallen by 60 to 70 per cent in parts of Johannesburg, which has some 3.2 million inhabitants and is the country's largest city.

South African police spokesman Vishnu Naidoo confirmed an overall drop in crime during the World Cup, the paper said, but he declined to give details
