'Police will never check a database only to establish a victim's immigration status,' Mr Sawyer added.
'If an officer becomes aware that a victim of crime is suspected of being an illegal immigrant, it is right that they should raise this with Immigration Enforcement officers and not take any immigration enforcement action themselves.
'Throughout, the police should treat them as a victim of crime.
'The police priority is to protect victims and investigate crime, and we are extremely careful about doing anything to deter victims from reporting to us.'Illegal immigration is a crime. Isn't it?
Corey Stoughton, advocacy director at campaign organisation Liberty, said: 'We have repeatedly raised our concerns about this practice of sharing a victim's data with the Home Office and we are pleased the NPCC is finally addressing it.
'This inherently biased practice actively discourages victims and witnesses of crimes coming forward, leaving criminals to continue committing crimes with near impunity and victims with no recourse to justice.'What about our 'recourse to justice'?
She said the issue will persist unless there is a 'complete firewall' between police and the Home Office.In other words, 'Until we get the open borders we want, and our Common Purpose troops can move on to the next agenda item'.
