A faster and more efficient method of taking fingerprints which has been trialled by police in Worcester is to be rolled out across the force area.
The Livescan fingerprint machine in action in Worcester
Officers have been piloting the Livescan system since 2002.
It scans fingerprints and palms and the details are checked against a computer database and can be identified within five to 10 minutes.
The force now plans to introduce the system to Kidderminster, Redditch, Hereford and parts of Shropshire.
Other police forces are also using the system.
