Firefighters have issued a reminder of their smoking safety advice following a fire at a block of flats on Duncan Terrace in Islington.
Half of a maisonette split between the ground and first floor was damaged by the fire. One man left the building before the Brigade arrived and was taken to hospital by London Ambulance Service.
The fire is believed to have been accidental and caused by the unsafe disposal of smoking materials.
A London Fire Brigade spokesperson said: "If you smoke it is vitally important you stub it right out, preferably in an ashtray.
"Always ensure your cigarette is completely out when you’ve finished smoking it. If you don’t, you risk causing a fire as you don’t know what it may land on which could potentially start a fire."
The Brigade was called at 2036 and the incident was over for firefighters at 2127. Four fire engines and around 25 firefighters from Islington, Shoreditch, Euston and Soho Fire Stations attended the scene.
