The Stop and Scan Process

1. An Offence - Officer’s discretion as to what constitutes an offence, littering or traffic offences count. 

2. Scan - Officer judges whether the person is 'who they say they are' based on looking at them

3. Search - Officer can search the criminal database and/or the Home Office database

4. Home Office Flag - A flag is returned if there is any activity associated with the person, eg if they have a visa

5. Call Home Office - If a flag is returned, the officer must call Home Office Command and Control

6. Detention - Home Office enforcement may then put the person in indefinite detention, or deport them.
