Arrests were made in Wellingborough and Kettering as a series of Operation Guardian raids to tackle burglary and vehicle crime took place.
More than 130 officers flooded areas of the county as part of a High Impact Day to send a clear message to offenders that these types of crime will not be tolerated.
A total of 15 warrants were executed during the day – six in Northampton, five in Kettering and four in Wellingborough.
As a result, a quantity of stolen property was recovered as well as an amount of cannabis plants and class A and B drugs.
A total of 11 people were arrested, seven of which were for burglary offences.
Four were arrested in Northampton, three in Kettering and four in Wellingborough.
Other activity included an automated number plate recognition (ANPR) operation where officers carried out stop checks of vehicles.
Officers visited a number of scrap metal dealers and second hand dealers across the county to deliver warnings about stolen goods, and plain clothed patrols took place in hot spot locations for burglary and vehicle crime.
Detective Chief Superintendent Simon Blatchly said: “The day was a great success and we will continue to carry out enforcement activity as part of Operation Guardian, as well as prevention activity that is taking place daily to reduce burglary and vehicle crime.”
