The bus, heading for Strandfontein and San Remo, was standing in traffic opposite the new housing development in Pelican Park close to the KFC when the skelms attacked.
Commuters were horrified as windows were smashed by a group of men who had realised the driver could not move the bus.
Traffic on the road has become a nightmare due to road works.
A female passengers says the skollies stoned the right-hand side of the bus.
“Everyone on the right side of the bus got up and moved into the aisle. We were all in shock and screaming for the driver to get us out of there, but there was nowhere to go,” says Samantha Carelse, 40.
“They threw out three windows and robbed people in the front of the bus. Three guys hopped in through the window and just took what they wanted.
“The others continued to throw bricks at the bus and it was the longest two-minute pause in traffic I have ever had.
