The Impact Nominal Index (INI) is designed to enable the police to find out instantly if any other UK force holds information about their suspect. In the past this information would not have been visible beyond the records of the force holding them.

Commenting on the INI, Home Office minister Hazel Blears said, The ability to share information across police force boundaries is the key to effective policing at the national level.

The INI is the first step in our plans to provide a national information sharing capability which will prevent criminals from escaping detection simply by crossing force boundaries. This will increase public protection and help create safer communities, added Ms Blears.
