A woman was treated at the scene of a blaze at a suspected cannabis factory.

Emergency serives were called to a fire at a house being used as a suspected cannabis factory in Station Terrace, Queen's Park, on Saturday at 8.28pm.

One woman was treated at the scene by London Ambulance Service crews and firefighters wearing breathing apparatus rescued two cats using a ladder.

Four fire engines and around 25 firefighters tackled the blaze, which was under control by 11.30pm.

Part of the ground floor hallway was damaged in the blaze. The cause of the fire is under investigation.

A London Fire Brigade spokesperson said: “Cannabis factory fires can be particularly dangerous because of the way criminals use unsafe wiring to illegally obtain electricity in order to grow the plants.

"They're often in top floors or lofts which means when a fire takes hold it spreads, destroying roofs and damaging neighbouring buildings.

"Firefighters can also be exposed to risks when dealing with the fires because of bad wiring and traps at some of the properties.

"It's important that people know the key signs and inform the police so that they can act swiftly to prevent these dangerous fires from happening."

Firefighters from Willesden, North Kensington, Paddington and West Hampstead fire stations attended the scene.
