Two fire engines were called to a garden shed alight in Cricklewood last night.
The wooden shed at a property in Cotswold Gardens was completely damaged by fire.
The shed contained two fire cylinders and firefighters were able to effectively cool the cylinders to ensure they did not explode.
The Brigade was called at 1731 and the fire was under control at 1907. Crews from Hendon and Willesden fire stations attended the scene.
