Four men have been arrested in connection with drug dealing in Leeds, Darlington and Harrogate.
Two men were arrested at addresses in Leeds and two men were arrested in Manchester on Tuesday (February 25).
Large amounts of Class A drugs and cash were recovered.
All four were arrested on suspicion of conspiracy to supply Class A drugs and remain in custody.
As part of Programme Precision, which is West Yorkshire Police’s ongoing initiative to tackle serious and organised crime, officers from the Leeds District team worked with colleagues in Durham Constabulary, Greater Manchester Police and British Transport Police to make the arrests.
Detective Inspector Phil Jackson, of the Leeds District Precision Team, said: “The arrest phase executed today alongside our colleagues from other forces has been the culmination of many months of painstaking work by specialist officers to identify those we suspect of being involved in these county lines drug dealing operations.
“County lines dealing is something we are continuing to take very seriously given the wide scale risks and harms it presents to our communities, and the public have a key role to play in alerting us to anything suspicious that could assist our work.
“It might be an increase in comings and goings at a particular property or a concerning change in the behaviour of young person or vulnerable resident. People should let us know anything that concerns them in that way as it might form part of the wider intelligence picture that we are already building up.
