A Derbyshire police officer is being investigated over accusations they used AI to "create evidence".
The Crown Prosecution Service (CPS) said it was working with Derbyshire Police to investigate the use of AI by an officer.
The officer is accused of using the technology to create evidence in a "number of cases", according to Derbyshire Police.
The CPS said it is "engaging with" defence teams and courts which may have been affected by the alleged conduct.
The officer has been taken off frontline duties pending the outcome of the investigation, and no arrests have been made.
This comes after PoliceAI, a national centre for AI in policing, was launched this week.
At the launch on Wednesday, PoliceAI interim director Alex Murray said: "Crime and technology are evolving rapidly.
"Policing must keep pace by adopting AI responsibly to catch criminals and keep people safe."

Earlier this year, the West Midlands police chief was forced to apologise after it was revealed his officers relied on false information supplied by AI when deciding to ban fans of an Israeli football club from attending a match against Aston Villa in Birmingham.
Maccabi Tel Aviv fans were barred from travelling to the game by the local Safety Advisory Group (SAG), which cited safety concerns based on advice from the police force.
This included a reference by the force to a fictional match, fabricated by AI, between the Israeli club and West Ham United.
