Golden Arrow bus service says another bus was torched in Mfuleni on the Cape Flats late Monday night.
This means eight buses have been set alight since taxi violence broke out in nearby Nyanga and Philippi on Monday.
One person was killed and several bus drivers assaulted.
Buses with armed escorts have been deployed to transport commuters to work on Tuesday.
Golden Arrow spokesperson, Bronwen Dyke says: “Golden arrow can confirm that another one of our busses were set alight last night at 8pm just outside Mfuleni at Malibu circle. We are therefore taking some precautionary measures this morning and not going into certain areas. We ask that our passengers from Samora Machel please make their way to Vanguard drive, our Nyanga passengers to the N2 and Borcherds Quarry and Mfuleni passengers to Malibu circle.
