Operation Hawk is targeting low-level drug dealers who operate at street level - Home Office figures say that up to half of acquisitive crimes, such as burglaries and muggings, are carried out to pay for drugs.
The officer in charge of Operation Hawk, Commander Mak Chishty, has urged the local communities to help: "We need to encourage communities to talk to us and report concerns, and we will reward this trust by delivering swift results and telling people what action we have taken. Community intelligence passed to us will be dealt with as quickly as possible and carefully assessed before any action taken.
"With your help we can make your local neighbourhood safer. You make the call, we'll make it stop."
