Key facts
- UK police are developing a national AI system called PoliceAI to streamline investigations.
- The initiative aims to save up to 6 million working hours annually by automating data processing.
- PoliceAI will focus on digital evidence processing, transcription, summarization, and data linking.
- Early trials demonstrated significant improvements in reviewing large volumes of digital data.
- Pilots are scheduled through 2026-2027, with a focus on audio/video redaction and AI-enabled crime response.
- All AI systems will undergo independent testing for accuracy and bias before deployment.
The United Kingdom is developing a national artificial intelligence system, dubbed PoliceAI, to enhance the efficiency and consistency of crime investigations across all police forces. This initiative aims to tackle the significant time police officers spend sifting through vast amounts of digital data, such as CCTV footage, phone records, and reports.
Backed by a substantial £75 million investment over three years, PoliceAI will serve as a central hub for identifying, testing, and scaling effective AI tools. The system is designed to automate time-consuming tasks, including the review of extensive video files, transcription of audio recordings from emergency calls, and summarization of case documents. AI-powered data linking functions will also help connect fragmented information across various police databases.
Early trials have demonstrated the potential of AI in accelerating investigations. In one instance, approximately 800 hours of CCTV footage from a kidnapping case were analyzed in just three hours, contributing to an early guilty plea. Another trial saw large digital datasets, equivalent to half a million e-books, processed instantly to aid in a serious organized crime investigation.
Pilots for PoliceAI are set to continue through 2026 and 2027, with a particular focus on audio and video redaction capabilities, which are expected to save up to 1 million working hours annually. The system will also bolster policing's response to AI-enabled crimes, such as deepfakes, through a dedicated threat hub and officer training. Furthermore, AI tools will support investigations into retail crime and tool theft by tracing ownership of recovered items.
As part of its integration into the UK's National Policing Service framework, PoliceAI will involve a public registry of deployed AI tools, developed in partnership with CENTRIC at Sheffield Hallam University. All AI systems introduced will undergo rigorous independent testing for accuracy and bias to ensure reliability and fairness, maintaining human accountability.
