Four fire engines and around 25 firefighters tackled a fire at a tanning salon on High Road in Wood Green.
Most of the ground floor salon was damaged by fire. Three people were treated on scene by London Ambulance Service crews after suffering from smoke inhalation.
The Brigade’s Control Officers took the first of 11 calls to the fire at 1452 and mobilised crews from Hornsey, Stoke Newington, Edmonton and Holloway fire stations to the scene. The fire was under control by 1605.
The fire is believed to have been accidental and caused by the failure of a cooling fan for a sunbed.
