Senior Met Police Officer Suspended After AI Surveillance Tool Flags Sexual Content on Work Phone

A senior Metropolitan Police officer has been suspended after an AI-powered surveillance tool reportedly detected sexual content on his work-issued phone, marking one of the most prominent individual cases to emerge from a controversial internal monitoring operation.

The Officer and the Allegation

Special Chief Officer James Deller, who commands approximately 1,200 Special Constabulary officers, is under investigation following the discovery of what has been described as “sexualised content” on a work device. The Metropolitan Police confirmed he has not been arrested and that no criminal allegations have been made.

“The officer has not been arrested and there are no criminal allegations,” a Met spokesperson said. The matter is being treated as a disciplinary issue, which could result in dismissal if the allegation is substantiated.

The Palantir Deployment

Deller’s case is one of more than 100 referrals generated by a one-week deployment of software developed by Palantir, the data analytics company co-founded by billionaire Peter Thiel, a prominent financial backer of US President Donald Trump.

The platform operates by connecting and searching across disconnected datasets already lawfully held by the Met — including work phones and laptops — to identify potential misconduct. Alleged violations ranged from breaches of working-from-home rules to suspected corruption and serious criminal offences including rape.

The scale and speed of the referrals generated by a single week of operation underscore both the surveillance reach of the technology and the questions it raises about due process, proportionality, and oversight.

A £50 Million Contract Blocked

The internal deployment comes amid a broader and unresolved dispute over a proposed £50 million contract between the Met and Palantir for automating intelligence analysis in criminal investigations — a deal first reported by the Guardian in April.

London Mayor Sadiq Khan has blocked the contract, with his office stating that the procurement process had not “adequately ensured or demonstrated value for money,” citing the Met’s failure to engage with more than one potential supplier.

Khan is also understood to be seeking government guidance on whether a company’s ethical record should be a formal consideration in public procurement decisions — a question with direct relevance to Palantir, whose technology has been deployed in US immigration enforcement and military operations.

Palantir responded by accusing Khan of “putting politics above safety.” The company also holds existing contracts with the NHS and the Ministry of Defence.

Accountability and Oversight Questions

The use of AI tools to conduct bulk surveillance of police personnel — without, as far as is publicly known, individualised suspicion prior to scanning — raises significant questions under UK data protection law and human rights frameworks, including Article 8 of the European Convention on Human Rights, which protects the right to private life.

Whether the Met obtained meaningful consent from officers, conducted a lawful data protection impact assessment, and applied appropriate proportionality tests before deploying the technology has not been publicly confirmed. Those questions remain unanswered.
