Emergency services are battling a fire along M1 south after the Smit Street in in Braamfontein, Johannesburg.
Preliminary investigations indicate that yet another incident of suspected cable theft and vandalism may have caused the fire.
Power supply has been affected in areas including Braamfontein, Parktown West, Newtown junction, De Korte North and Smith west.
The affected cables run between the Braamfontein and Fordsburg substations.
Johannesburg Emergency Services are currently on site extinguishing the fire and will thereafter ventilate the tunnels to remove smoke and ensure the area is safe for entry.
