Police deploy new £26m crime mapping system to target knife crime areas

A £26 million government fund will target knife crime hotspots with surgical precision, using advanced mapping technology that pinpoints danger zones down to individual streets and the specific times of day they are most dangerous.
The Knife Crime Concentrations Fund, announced by the Home Office, will be allocated to the 27 police forces in England and Wales that deal with 90% of all such offences. Its strategy is built on a key insight: the vast majority of knife crime is concentrated in a very small number of persistent locations. Policing Minister Sarah Jones said the government aimed to halve knife crime within a decade, stating: “Knife crime devastates lives and families across the country, and the majority of it takes place on just a small number of streets.”
How Hyper-Local Crime Mapping Works
At the core of the initiative is national mapping technology being shared with forces, capable of identifying hotspots as specific as 100 square metres. The system does not just map locations; it integrates temporal and geospatial data, analysing not only *where* crimes cluster but also *when* they are most likely to occur. This allows for hyper-targeted interventions.
The mapping leverages data shared between police, councils, and social services, including criminal records, incident reports, and behavioural patterns. This builds upon previous Home Office schemes like the Safer Streets Initiative by using deeper, more sophisticated analysis to enable early intervention. The minister referred to this as “innovative Hex mapping technology” designed to pinpoint hyperlocal trouble spots.
This proactive, data-led approach is already showing results in some areas. West Midlands Police, using similar geospatial analysis under “Project Guardian” to identify risky facilities like nightclubs within hotspots, reported a 16% reduction in knife crime, over 800 arrests, and the seizure of more than 500 weapons in the past year.
Targeted Police Tactics in the Zones
In the zones identified by the mapping, forces will deploy a combination of increased patrols and technology. The funding will support new CCTV cameras, knife detection arches, and live facial recognition (LFR) systems.
LFR, used to identify individuals on police watchlists in busy areas, has already led to arrests. A deployment in Croydon resulted in 15 arrests for various offences, though the technology has faced legal challenges and concerns over discrimination. Knife arches are seen as an effective deterrent; the nationwide Operation Sceptre in 2023, which included their use, led to the removal of nearly 10,000 knives and almost 1,700 arrests.

The push towards data-led policing is set to evolve further. The Home Office is developing AI-powered crime mapping prototypes, due by April 2026, which aim to predict and prevent serious crimes by analysing shared data. The department has also previously funded research into technologies using radar and acoustic sensors to detect concealed knives.
The National Picture and Youth Intervention
The crackdown comes against a backdrop of complex national trends. In the year ending March 2025, there were approximately 53,000 offences involving a sharp instrument in England and Wales—a slight decrease from the year before and about 4% lower than before the pandemic. However, certain offences have risen sharply: knife-related rape increased by 23.4%, and threats to kill by 6.5%. Of the 262 homicides using a sharp instrument in the year to March 2024, 46% of all killings involved a knife.
Regional disparities remain stark. The Metropolitan Police area recorded 182 offences per 100,000 people in 2024/25, the highest rate in the country and far above the lowest rate of 31 in Cumbria. London, Birmingham, Middlesbrough, and Manchester are known persistent hotspots. Youth involvement is a central concern, with those aged 10-17 comprising around 18% of offenders in knife possession cases, and reports of children as young as seven being found carrying blades.
Alongside enforcement, the government’s wider “Protecting Lives, Building Hope” strategy emphasises prevention. A new generation of youth centres, called Young Futures Hubs, will be rolled out. The first eight will open in Birmingham, Brighton and Hove, Bristol, County Durham, Leeds, Manchester, Nottingham, and Tower Hamlets, with a plan for 50 eventually. They aim to provide joined-up support on mental health, employment, and crime prevention for 10–18-year-olds, working with multi-agency panels to steer at-risk young people away from violence.
A separate £1.2 million scheme will use the same Home Office mapping technology to identify up to 250 schools at greatest risk of knife crime, offering training and intensive support to 50 of them.
