Passengers were evacuated from a double-decker bus in Marylebone after a fire in its engine bay.
Firefighters were called to the blaze in Portman Square at 4.25pm on Tuesday (January 10).
All passengers had left the vehicle before the Brigade arrived, London Fire Brigade said.
One man was treated on scene by London Ambulance Service crews for smoke inhalation.
The fire was under control by 4.45pm.
The rear of the vehicle was damaged.
The Brigade’s 999 Control Officers took 18 calls about the blaze and one fire engine from Soho Fire Station was sent to the scene.
The fire is believed to have been accidental, but the exact cause has been recorded as undetermined due to the level of damage within the engine bay.
