The Metropolitan Police has launched internal investigations into hundreds of officers after deploying an artificial intelligence system developed by US tech firm Palantir Technologies to identify misconduct within its ranks.
The AI tool was used over the course of a week to analyse internal police data already accessible to the force. It flagged a wide range of alleged breaches, from working-from-home rule violations to serious accusations including corruption, sexual offences and other criminal behaviour.
According to the Met, the system helped uncover evidence linking a small number of officers to serious misconduct cases, resulting in the arrest of three officers on charges including abuse of authority for sexual purposes, fraud, sexual assault, misconduct in public office and misuse of police systems.
The largest category identified by the AI tool related to corruption and misuse of internal systems. Around 98 officers were assessed for allegedly exploiting shift-rostering systems for personal or financial gain, while a further 500 received preventative notices over similar concerns.
In addition, 42 senior officers, ranging from chief inspector to chief superintendent, are being investigated for alleged serious non-compliance with workplace rules. This includes claims that some falsely reported being in the office while working remotely or being absent for extended periods, in breach of the Met’s attendance policy requiring at least 80% office presence.
The AI system also flagged undeclared interests, including membership of the Freemasons, which is now required to be disclosed. Twelve officers are under investigation for gross misconduct over alleged failure to declare membership, while another 30 have received warning notices.
The use of AI marks a further step in the Met’s growing reliance on technology in policing, alongside tools such as drones and live facial recognition systems. The force has also been in discussions about expanding its use of Palantir technology in criminal investigations.
Palantir has faced wider political scrutiny due to its contracts with US immigration authorities and the Israeli military. In the UK, its work with the NHS has previously attracted criticism from MPs, with calls for a £330 million contract to be scrapped.
The Met said the AI system is designed to “build trust, reduce crime and raise standards”, arguing that modern policing must keep pace with technological change both on the streets and within the organisation itself.
Met Commissioner Sir Mark Rowley said the force must adapt to evolving risks:
“Criminals are constantly adapting how they use technology and policing has to keep pace, not just on the streets but within our own organisation.
This is the Met using technology, data and stronger legal powers to confront poor behaviour, raise standards and fix our foundations as our communities would expect.
The vast majority of our officers and staff serve London with dedication and integrity and rightly expect us to act firmly against those who abuse their position or undermine public trust.
By bringing together the information we already lawfully hold, we can identify risk earlier, act faster and be fairer and more consistent.”
The investigations remain ongoing, with further disciplinary action expected as the analysis of AI-flagged data continues.
