South African police say they have arrested four men in the capital, Pretoria, for attempting to sell what they describe as an industrial nuclear device to undercover officers.
The men - all South Africans - were arrested Friday at a Pretoria gas station, where they attempted to sell the device for about $6 million.
Police say Interpol was also involved in the operation. They did not say where the device came from or for what industrial purpose it is used, but did say it contained radioactive material.
The officials say the four will appear in court soon to face charges of possession of a radioactive device, as well as health code violations for handling radioactive material in public.
Some information for this report was provided by AP, AFP and Reuters.
