Firefighters spent almost two hours bringing a blaze at a suspected cannabis factory under control.

London Fire Brigade (LFB) was called at 6.53am this morning to a house in Wellington Road, Wealdstone.

Four fire engines and around 25 firefighters worked to extinguish the blaze, which was under control by 8.45am.

A fire brigade spokesperson said it is suspected that the house was being used as a cannabis factory, and the cause of the fire is now under investigation.

They added: “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."

Fire crews from Harrow, Stanmore and Northolt fire stations all attended the scene.
