UK to spend £15M on AI-powered crime mapping in knife violence crackdown

What the funding will do

The Home Office is committing £15 million over three years to sharpen crime mapping across England and Wales, aiming to help police target knife‑crime hotspots with greater precision. The national tool slices the country into 1.46 million hexagons of about 0.1 km² and — it has been reported that — all knife offences recorded between April 2024 and March 2025 occurred in fewer than 2.5% of those cells. The figures are stark: one central London hexagon covering Leicester and Trafalgar Squares logged more than 45 knife crimes in that year, while a neighbouring cell saw fewer than five.

How it will be used — and the controversies

UK Research and Innovation (UKRI) will develop improved visualisation, add new data layers and apply AI to spot patterns and "drivers" of violence, the government paper says; it has been reported that ministers hope the micro‑geography will let partners deploy policing, prevention and services more surgically. The Home Office also says it spent £5m on hyperlocal pilots last year and plans £26.25m this year across 27 forces, funding patrols, wand and arch screening, more CCTV (including retrospective facial recognition) and targeted Stop and Search. The plan includes expanding live facial recognition from 10 to 50 vans — a move already criticized after a Cambridge University study found the tech was likelier to misidentify Black people, and Essex Police briefly suspended its use.

Will this be a surgical fix or a wider surveillance sweep? That’s the emotional knot here: communities that feel under threat want fewer stabbings; communities that feel watched fear new tech will widen bias and erode trust. The government frames the programme as part of a push to halve knife crime; critics warn that algorithmic mapping and behaviour‑detection research risk entrenching policing that "spots" people rather than addresses root causes.
