Two executives of a South African firm were arrested in Zimbabwe on Tuesday on charges of stealing diamonds from the controversial Chiadzwa diamond fields.

The two work for Canadile Miners, a joint venture between a South African company and the Zimbabwean government.

The men were arrested at a roadblock near Hot Springs, a holiday resort where most of the Chiadzwa mining personnel are camped.

Their lawyer, Victor Mazengero, told Eyewitness News he cannot speak to the press until he has permission from his clients.  But reports said the two were found with 57 diamonds worth R280 000. The diamonds were apparently packed in plastic in their car.

The arrests will only heighten the controversy over the Chiadzwa diamonds and the companies selected to exploit them.

MPs have been hearing that one of the firms chosen by the Mines minister has no history in diamond mining.

There are also claims that some of the members of Canadile’s board have been accused of gem smuggling in the Democratic Republic of Congo.
