SIX fire engines and around 40 firefighters were called to a blaze at a bungalow used as a suspected cannabis factory in Strathearn Avenue, Harlington, yesterday (25).

Part of the bungalow was damaged, but there were no reports of any injuries.

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 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 they can act swiftly to prevent these from happening."

The brigade was called at 2.35pm and the fire was under control by 4.02. Crews from Feltham, Heathrow, Heston, Hayes, Hillingdon and Southall attended.

As yet, it is treating the cause as undetermined.
