An attempt was made to run over six men as they were walking home from synagogue in a suburb of Johannesburg last month.
In the incident, which was reported last week, a vehicle with four occupants drove past the men, with the driver making offensive hand gestures and shouting "F---ing Jews".
A few minutes later, the vehicle returned and swerved lanes, threatening to knock the men over.
The six men were described as "identifiably Jewish".
