BLACKBURN with Darwen Police are asking for the public's help in trying to cut out crimes.

They posted on their Facebook page: "If you see a roof like this it could mean there is a cannabis factory inside, the proceeds of which will help to fund organised crime.

"Give us a call on 101 and we will apply a different kind of heat to those responsible!"

They also added: "The industrial scale production of cannabis is used to fund organised crime, this means; People trafficking, Prostitution, Drug smuggling, Serious violent crime, Gun crime, Gang related crime and terrorism.

"Whilst you make take the view 'it is only a bit of weed, there is no harm in that' for the innocent people who are caught up in the wider issue of organised crime the effects are life changing.

"It could be happening on your street.

"We need your help to do this and we hope that you see how important this is as an issue and call us if you have any suspicions."
