Western Cape police spokesperson Colonel Andrè Traut said the second bus was torched in Baden Powell Drive, Strandfontein.
He said circumstances surrounding the second incident are under investigation.
"Unknown suspects petrol bombed the bus and fled the scene. One commuter suffered severe burn wounds and two were treated for minor injuries. The bus was destroyed by the fire. The motive for the incident is yet to be established," said Traut.
