Hundreds of people have been seen leaving their businesses and walking down Rivonia Road following an alleged bomb scare in Sandton, Sandton Chronicle reports.
There is a heavy police presence including police vans, the bomb squad and fire trucks.
An Alexander Forbes employee who wished to remain anonymous said: “We were told by our safety officer to evacuate the building. We were told to walk up Rivonia Road and make our way down 5th to a safety point.”
Earlier, Gautrain users were unable to access the entrance, and Rivonia Road was closed, but has since reopened.
