Station Commander Jerry Barker, who was at the scene, said: “The fire had started on the fifth-floor balcony of a 10-storey block of flats.
“Firefighters worked hard in very hot conditions to quickly bring the blaze under control and minimise damage to the affected flat.”
The Brigade’s 999 Control Officers took 16 calls to the blaze.
The Brigade was called at 1842 and the fire was under control by 1935. Fire crews from Bethnal Green, Holloway, Homerton, Poplar and Soho fire stations were at the scene.
