A woman's body was found in a warehouse destroyed in a fire in Neasden, north London.
About 70 firefighters spent nearly four hours fighting the fire directly on North Circular Road.
After the fire was under control, the crew searched the three-story abandoned building and found the woman's body.
The cause of the fire is being investigated, said the London Fire Department (LFB).
Ten fire engines – from Willesden, Park Royal, Wembley, Hendon, Stanmore and West Hampstead – were set on fire at 02:38 BST.
As a precaution, 17 people were evacuated from the surrounding buildings and the fire was brought under control around 06:20.
The North Circular Road was blocked in both directions while the fire was being fought.
Station Manager Robbie Robertson said, "Firefighters worked extremely hard overnight to prevent the fire from spreading to an adjacent building."
