The fire started on Tuesday morning and officials say they have reason to believe that arson was committed.

The heat and humidity served for vicious flare-ups that occurred across the mountain.

Late yesterday afternoon, ground crews were assisted by four aircrafts.

The 1,400 hectare devastation was visible on the slopes.

Meanwhile, an investigation has been launched into another fire that broke out along the Glencairn Expressway in the South Peninsula.

Fire crews had to endure strong wind conditions as they battled the flames yesterday. The blaze was eventually brought under control. Cape Town's hot and dry summer conditions often make it susceptible to wildfires. Last year was particularly devastating, with 5,000 hectares of vegetation being burnt.

The fire took four days to bring under control and damaged or destroyed 13 homes.
