JOHANNESBURG - There've been two major drug busts in the country over the last week.
In one, an industrial-scale meth lab was busted in Groblersdal in Limpopo.
In the other, cocaine to the value of R252-million was seized in Stilbaai in the Western Cape.
Foreign nationals were arrested alongside locals in both cases.
Three Mexicans were arrested in Limpopo and a Russian national was arrested for the cocaine.
Martin Ewi, an organised crime expert at the Institute for Security Studies, talks about these arrests.
