And now a total of 23 people are behind bars after being sentenced for their roles in illegal drug operations.
Their combined sentences will stretch for 50 years - but police have already stressed that more will follow.
They began Operation No Deal in Wolverhampton 18 months ago and launched several dawn raids late last summer.
A few months later those involved - 23 men, one woman and one youth - have been put through the court system and sentenced.
The aim of the Wolverhampton No Deal campaign was to rid the area of street level drug dealing.
To do this it targeted key drug dealers but also aimed to reduce the demand for drugs by pointing users towards drug treatment schemes.
And a total of 25 people have now been sentenced after pleaded guilty to class A drug dealing.
The longest prison term was given to Lance Wafer, aged 27 and of Luce Road in Low Hill, who was jailed for five years.
Fellow Low Hill men Gary Newton, 38 of Fourth Avenue and Patrick McNeil, 22 of First Avenue, were given four years.
Today police chiefs welcomed the sentences handed down at Birmingham Crown Court, but warned criminals that their investigations were continuing apace.
Wolverhampton Police Superintendent Paul Drover led the operation.
He appealed for the public's support in continuing to crack down on drug dealing.
He said: "This latest phase of court appearances is by no means the end, we will continue to work with our partners to try to eradicate drugs from the city's streets and help those individuals who wish to break their drug addiction.
"We are very aware that by taking action against a number of individuals, this opens the door to the next wave of dealers.
"We will continue to do everything we can to try to stop this happening and take action against those criminals.
"We need the public's continued help and would encourage anyone with information about dealing or drug taking in their area to call us.
"I hope we have shown that we take all information very seriously and will act upon it."
Other long sentences were handed out to Gavin Williamson, of Heath Town and Antoine Miles, from The Scotlands.
Williamson, 28 of Burton Road and Miles, 23 of Kipling Road, both got four years while Aaran Tanner-Khan, 27 and of Wood End Road, Wednesfield, received a term of three years and nine months.
Meanwhile teenager Keelan Burke, 19 and of Dovedale Avenue, Willenhall, was jailed for three years.
Three-and-a-half-year terms were given to Shenrick Campbell, 20 of Field Street, Springfield, Sam Rogers, 22 of Snape Road in Ashmore Park and Scott Cousins, 31 of Orchard Road in Wednesfield.
Michael Lewis is led away in handcuffs after being arrested
A 17-year-old boy, who cannot be named for legal reasons, was given a 12 month conditional discharge and ordered to pay £200 costs.
Last summer police said that as a direct result of Operation No Deal they had seen an increase in the number of people calling them to give information on gang and drug activity.
Officers began gathering intelligence on people dealing hard drugs in specific areas of the city 18 months ago.
Last September police swooped on these people during a series of early morning raids, when 48 people were arrested.
The first took place in Heath Town, Park Village, Ettingshall and Willenhall on September 24, when 280 officers swooped on 14 addresses.
Police chiefs said they had sent a message to criminals in the city and that the operation was based on significant and extensive information collated by a dedicated team of officers.
The No Deal raids followed months of undercover surveillance.
Police formulated the operation after a series of shootings in the city in early 2012.
They talked to people throughout Wolverhampton who told them that gangs and drug dealing were significant issues that needed to be tackled.
A large team of officers collected what chiefs described as 'significant and extensive information' before planning the raids.
