British police forces have signed contracts with a controversial US tech giant to buy AI-powered software that uses data about an individual’s race, sex life, health and political beliefs, it can be revealed.

An internal police memo obtained by The i Paper and Liberty Investigates confirms an intention to “nationally” apply the “Nectar” intelligence system, currently deployed as a pilot by the Bedfordshire force after being developed with Silicon Valley data analysis group Palantir Technologies.

The document, obtained under freedom of information rules, shows how the Palantir system is designed to bring together dozens of existing law enforcement databases into a single computing platform to draw up detailed profiles of suspects, as well as collate information on victims of crime, witnesses, and vulnerable individuals including children.
