Crimestoppers has launched a campaign across the North West and North Wales to encourage reporting on criminal gangs.

The independent charity's campaign features a social media advert using a snake to illustrate how gangs 'increase their grip on communities', leaving them in fear and with a feeling of helplessness.

Crimestoppers said criminals exploit people and bring violence and damage to communities.

They said gang members are often known in the areas they operate, but there is a 'reluctance' to report their illegal activities.

The charity said the same gang may be involved in the sale of illegal drugs and cannabis cultivation, as well as the exploitation of young people and the vulnerable through county lines, modern slavery, sexual exploitation, illegal immigration, the importation and use of guns, illegal money lending and money laundering.

Crimestoppers said the key to making the North West a safer place to live and work is to pass on information completely anonymously to Crimestoppers so that law enforcement can act.

Gary Murray, North West regional manager at the charity Crimestoppers, said: "Help us loosen the grip of criminal gangs across the North West.

"Only by individuals taking the brave step of reporting anonymously what is going on in their areas to our charity will we see a cut in the pain and suffering that our communities face.

"The information you and others come forward with may help save lives and make your area safer for you and your family.

"Over the last six months, from the North West and North Wales we have received over 20,000 pieces of 'actionable' or high-quality information.

"This has led to a significant number of arrests, millions of pounds of drugs seized and weapons being taken off our streets."
