ANGOLAN security forces have arrested two South Africans accused of bringing cocaine worth an estimated $2m into the country. Customs officials found 60kg of the drug hidden in containers on a flight from Rio de Janeiro in Brazil by the Angolan national carrier TAAG. The South Africans, who were not named, are accused of organising drug trafficking with a number of Angolans. The Angolan government early this year boosted the customs force with narcotics experts to crack down on drug dealing.
