Police officers are being given mobile finger print scanners to instantly identify suspected criminals and illegal immigrants.
Two hundred and fifty of the new pocket-sized devices are being trialled in West Yorkshire before being rolled out by the Home Office across the country.
The scanners, which cost less than £300 each, can be used by any officer to take two fingerprints from a suspect.
They are then checked in seconds against records held in two national databases of fingerprints called IABS and IDENT1.
