Ten fire engines were called to a fire in a block of flats by the North Mall and Plevna Road in Edmonton Green this evening.
Brigade control officers received nearly fifty calls about the fire which was very visible.
Part of a four bedroomed flat on the 6th floor was alight. Crews wearing breathing apparatus led one man to safety through an internal staircase and around 50 residents left the block before the arrival of the Brigade.
Ten fire engines from stations including Tottenham, Chingford and Southgate fire stations were at the scene.
The Brigade was called at 1739 and the fire was under control by 1910.
The Brigade believes that a carelessly discarded cigarette, match or ash from a barbecue could have caused the fire. The Brigade said the case highlights the need to take care with such items at all times.
