Firefighters have issued a safety reminder after a fire at a restaurant on Devons Road in Mile End.
Part of the ground floor of the building was damaged by the fire and the ducting (extraction system) from the ground floor to the roof was destroyed. There were no reports of any injuries.
The Brigade's fire investigators believe the fire was accidental and was caused by burnt food on a grill igniting the ducting above.
A London Fire Brigade spokesperson said: "This is a timely reminder to make sure you never leave cooking unattended. If you do have to leave the room, turn the heat off.
"It's also vital to ensure ovens, hobs, cooker hoods and ventilation systems are kept clean to avoid a build up of fat and grease, which could ignite and cause a fire."
The Brigade's 999 Control Officers took 18 calls to the fire.
The Brigade was called at 2028 and the fire was under control by 0007. Six fire engines and around 40 firefighters from Poplar, Millwall, Bethnal Green, Whitechapel and surrounding fire stations were at the scene.
