A basement fire in a shop on Denmark Hill on Friday morning (October 8) took 40 firefighters and six fire engines over an hour to put out.
Part of the basement was damaged by the fire. London Fire Brigade said they had no reports of any injuries.
Station Commander Mark Nunan, who was at the scene, said: “On arrival, smoke could be seen coming from a flat roof and crews quickly assessed the scene to ascertain that it was coming out of a vent from a neighbouring shop.
“Everyone was out of the building before firefighters arrived and crews worked very hard to quickly bring the fire under control.
“Some congestion in the local area is expected this morning.”
Firefighters were called at 8.10am and the fire was under control by about 9.20. Fire crews from Brixton, Peckham, Old Kent Road, New Cross, Lambeth and Dowgate fire stations were at the scene.
The cause of the fire is unclear and firefighters are investigating.
