Police seized drugs and two people were arrested during a series of raids on homes in Wellingborough and East Northants.
Homes in Wellingborough, Bozeat and Rushden were searched on Wednesday, March 5.
A further search was also carried out in Northampton.
In Bozeat a cannabis factory was found and about 140 cannabis plants were seized.
A 28-year-old man was arrested and charged with drugs offences.
He was remanded in custody and is due to appear at Northampton Crown Court on March 26.
Following another search in Kiln Way, Wellingborough, a 35-year-old woman was arrested and charged with possession of cannabis.
Three other raids were also carried out – two in Rushden and one in Northampton – and enquiries are ongoing.
Chief Insp Chris Hillary said: “We have carried out a number of successful warrants over the past few days and we’re determined to keep up the pressure on those committing crime in our county.
“As well as continued enforcement activity, we’ve also been working with staff from partner organisations, including Trading Standards, Wellingborough Homes and the East Northants Council licensing team, visiting licensed premises and second hand dealers across the area.
“Officers have also been working alongside staff from Her Majesties Courts and Tribunal Services to carry out warrants in relation to non-payment of fines.”
Police officers have also been finding out what people are concerned about in their area as well as giving crime prevention advice and delivering property marking kits to a number of homes.
Smartwater property marking kits were delivered to 50 homes in Rushden and 52 homes on the Queensway estate in Wellingborough, and officers spoke to nearly 70 residents to find out their concerns and what they would like local police to focus on.
