There has been an urgent call on local communities to play a key role in the fight against drugs gangs.
With our police forces under increasing pressure to combat the threat of county lines drugs operations, one of the solutions could lie in neighbourhoods feeling confident in reporting what's going on.
The Crimestoppers charity is involved in a campaign in the East of England to get people to come forward.

The term 'County Lines' refers to criminal gangs from large towns or cities who move into a new area and take control of the local drug trade through violence and intimidation.
They then use a single telephone number, operated from outside the local area, to sell their drugs.
Norfolk alone has seen more than 1,000 arrests for county lines since December 2016 and the number of lines active in the county has nearly halved from around 50 to 27 over the past few years.

"The term County Lines is one that many people are only just becoming familiar with, so our charity is keen to raise awareness so we can prevent vulnerable people from being exploited and help keep our communities safe.
Police say the local community has a vital role to play in helping to identify vulnerable adults and children and gather evidence of illegal drug activity.
