Leicestershire Police has become the first force in the UK to use ‘facial recognition’ technology to identify suspects caught on officer body cameras and CCTV.
The computer software analyses the footage and compares images to tens of thousands on the force's database.
Hilary Gazzard, an Identification Officer, said it's helping save hours of police time trawling through images manually.
The software, works by matching up key facial features and measurements. It then narrows it down to the top 200 matches, which an officer will then look through.
Andy Ramsay, manager of the force's identity unit said it brings up a wide range of potential suspects.
Officers said the six-month trial, which is due to end in September, has already helped save hours of police time.
Though the results can't be used as evidence in court, Leicestershire Police said it is helping detectives develop new lines of enquiry.
Chief Inspector Chris Cockerill said he's pleased with how the trial has gone so far.
Police forces from other parts of the UK, and abroad, have contacted Leicestershire with an interest in the technology.
It's thought it could be used to help enhance security at airports and sporting venues.
