Dozens of people were forced to leave their homes after a fire ripped through a car workshop in north London.
Homes surrounding the workshop in Neasden were evacuated as thirty-five firefighters tackled the blaze on Friday night.
Up to 40 people were told to leave their properties because of gas cylinders at the scene of the fire in Village Way, London Fire Brigade said.
Firefighters were alerted to the fire at 4.40am and spent more than two and a half hours battling the flames.
An LFB spokesman said: “The single storey car workshop was completely gutted by the fire.
"Around 40 people were evacuated by police from neighbouring properties as a precaution due to gas cylinders on site, as some cylinders can explode when exposed to heat.”
The A406 was closed to traffic for the safety of drivers. No-one is thought to have been injured.
Fire crews from Park Royal, Wembley, Acton, Willesden and Hendon attended.
The cause of the fire is under investigation.
