The contraband represents 80 to 100 slaughtered elephants. Officers discovered the smuggled tusks aboard trucks in the city of Lubumbashi on Saturday, according to a legal official who declined to be named due involvement in an ongoing investigation into the affair. Police arrested five people but two fled after questioning, the official said. He added that the haul amounted to 1.5 tonnes. Both the origin and intended final destination of the ivory remain unclear.
