Police in Cambridgeshire have arrested 22 people and seized drugs, cash and weapons as part of a crackdown on county lines drug dealing and exploitation.

The national intensification week, which took place between October 11 and 18, saw officers execute 12 warrants and intercept vehicles potentially involved in county lines activity.

Four drug dealing lines were also dismantled using funding from the National County Lines Co-Ordination Centre.

County lines is the means of transporting illegal drugs from major cities like London and Birmingham into other areas, like Cambridge and Peterborough.

Children and vulnerable adults are often used to transport them, often at great risk to their own safety.

As a result of investigations carried out by Cambridgeshire Police across Cambridge, Peterborough and Wisbech, 17 people were arrested for drugs-related offences and a further five went on to be charged.

Class A drugs including crack cocaine and heroin were seized as well as cannabis, cash and mobile phones. Weapons including knives and a taser torch were also seized.

A number of potential cuckooed addresses, where drug dealers take over the home of a vulnerable person in order to use it as a base for dealing, were also visited.

Throughout the week officers were also speaking to hotel, bank, taxi and bus staff about spotting the signs of people being exploited by county lines. Neighbourhood officers also held talks at local schools to discuss the issue with young people.
