A speed camera in Carshalton was torched by vandals earlier this week.
The camera in Green Wrythe Lane was set alight shortly after midnight on Monday, May 5.
The arsonist set fire to a car tyre hung over the camera.
Eyewitness Tay Hassan said: "It was lucky the fire was put out quickly as it was spitting burning rubber everywhere."
