Police have sent a message to Merseyside drug dealers after four were arrested in North Wales.
It came after officers found a large quantity of hard drugs and cash at an address in Connah's Quay this week. The house was suspected to be part of a "cuckooing" operation.
Cuckooing is where people take over another person's house for criminal purposes. It takes its name from cuckoos who take over the nests of other birds. North Wales Live reports.
