JOHANNESBURG - There's been a surge in crimes of extortion in recent months.
So too have calls for a more coordinated approach and strategy to address the scourge.
Hardest hit are construction, transport and the informal sectors.
Roelof Viljoen from Business Against Crime SA said they're looking at a way to tackle this crime.
"While the criminals are eating away very small chunks in individual cases, it adds up to the economy having a big effect where we can't calculate the full amount expended," he said.
