LONDON — The Metropolitan Police launched investigations into hundreds of officers after deploying an artificial intelligence tool built by Palantir to monitor staff behavior over the course of a week. The software, which analyzed data the force already had access to, identified work-from-home violations, suspected corruption and criminal allegations including rape.

Three officers were arrested for offences including abuse of authority for sexual purposes, fraud, sexual assault, misconduct in public office and misuse of police systems. Corruption was the most consistent offense detected by the software.

Ninety-eight officers were assessed for misconduct related to abuse of the IT system that rosters shifts for personal or financial gain, while 500 officers received prevention notices for the same category of abuse. Forty-two senior officers, ranging in rank from chief inspector to chief superintendent, are being assessed for misconduct for serious noncompliance.

The force's guidelines require in-office attendance not to dip below 80%. Some senior officers falsely claimed to have been in the office when they were working remotely for excessive periods of time in violation of those guidelines.

Freemasonry membership is now a declarable interest within the force. Twelve officers are under investigation for gross misconduct for keeping their Freemasonry membership private, and 30 officers received prevention notices for suspected but uncorroborated undeclared membership.

The Met is negotiating to purchase Palantir technology to aid in criminal investigations.

"Criminals are constantly adapting how they use technology and policing has to keep pace, not just on the streets but within our own organisation," Met Commissioner Mark Rowley said. "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, particularly in leadership roles," he said.

"By bringing together the information we already lawfully hold, we can identify risk earlier, act faster and be fairer and more consistent," he added. "Alongside new vetting powers, this gives us the tools we need to remove those who should not be in policing and strengthen culture for the future."
