Hijackers in South Africa are placing cardboard boxes or plastic bags that contain or cover large rocks or chunks of concrete in the middle of the road.
They place up to three in the road, often in broad daylight, giving the driver little choice but to hit one of them.
When a car drives over these, it causes serious damage to the car and forces the driver to pull over.
As soon as the driver pulls over, hijackers ambush him/her.
Or, as happened to SAA cabin crew member Wesley Ford, he pulled up to avoid the rocks and and the hijackers took the opportunity to attack him…
