More than 1,000 people have been arrested and 292 weapons seized as part of a national crackdown on county lines drug dealing gangs.
Forces across the UK boosted activity in the week from May 17 with 1,100 arrests, 33 guns and 219 knives among weapons seized, and 80 drug dealing phone lines identified.
There are currently thought to be around 600 county lines gangs operating in the UK, down from around 2,000 two years ago.
The crime gangs are urban drug dealers who sell to customers in more rural areas via dedicated phone lines.
They are notorious for exploiting children to work as couriers and forcing vulnerable people to let them use their homes to conceal or deal drugs, as portrayed in BBC drama Line Of Duty.
During the week of action, 904 of these “cuckooed” homes were visited by law enforcement, and 1,138 vulnerable people were safeguarded.
National Police Chiefs’ Council lead for county lines Deputy Assistant Commissioner Graham McNulty said: “The police response to county lines has increased substantially over the past 18 months. We have been relentless in pursuing those behind the line whilst doing everything possible to rescue those being exploited.
“Intensification weeks like this allow us to dedicate a burst of activity and resources nationally, highlighting to the public our absolute determination to rid communities of this abhorrent crime.
“We will use all the powers available to us to tackle every element of the county line network because we know the effect violence and crimes associated with county lines can have in our communities.
“It is vital that everyone looks out for the signs of exploitation.
