The Metropolitan Police has been criticised over the pilot of a controversial AI tool to assess officers' device data, which its staff association described as "intrusive".
Developed by the US firm Palantir, the tool is being used to organise data the Met already lawfully holds, to identify potential concerns about officers' behaviour.
The Metropolitan Police Federation (MPF) warned colleagues to be "extremely cautious about carrying Metropolitan Police-issued devices when off duty".
Hundreds of officers are now being assessed for various forms of misconduct, including two arrests and two suspensions after potential criminal activity was flagged.
The federation said it was aware of an upgrade to the Lawful Business Monitoring software.
