Detective Chief Inspector Graeme Wright of Scarborough and Ryedale Command, said: “Drug dealing and the exploitation of vulnerable people associated with it remains a major priority for North Yorkshire Police.
“Working closely across the region with colleagues in other forces and agencies is vital if we are to disrupt the organised criminals who travel across borders to target North Yorkshire’s towns and cities. Today’s action is one of a number of operations over several months to target drug dealing in the Scarborough area"
