Raids across Merseyside and North Wales led to 10 arrests over a massive drug ring in the North West.
Police put doors in at 15 homes in connection with drug supply in Wirral and St Helens.
Six warrants were carried out by Merseyside Police in the Wirral area on Thursday.
During these raids, four people were arrested and a stolen vehicle was seized.
A further nine warrants were executed in the Blaenau Ffestiniog area by officers from North Wales Police on Thursday and Friday.
Six people were arrested and a quantity of Class B Controlled drugs and cash were seized.
The warrants followed a seven month County Lines drug supply investigation involving individuals from Merseyside and North Wales.
The investigation has previously located and seized two cannabis factories in St Helens totalling over 100 plants and seized Class A drugs and other drug dealing paraphernalia.
Four arrests were made for possession of Class A drugs and production of cannabis.
The four arrested have been released under investigation.
Detective Inspector Peter Stephenson of Merseyside Police said: “We remain committed to targetting the people responsible for serious and organised crime including drug supply.
“We have been working closely with colleagues in North Wales Police as part of this lengthy and ongoing investigation and I can reassure the communities of Merseyside that the force will continue its fight against those involved in drug dealing to make our neighbourhoods safer for everyone.
“I would also ask that people to continue to come forward with information so we can continue to take action.”
