Tens of thousands of innocent members of the public who report crimes are having their personal details stored on a ‘secret’ police database.
Those calling 999 about an incident or witnesses to crimes are routinely being asked for their ethnicity and date of birth, it has emerged.
The details are being kept without their knowledge on a ‘Big Brother’ file – where thousands of suspected criminals’ details are also held.
On the database of one force alone, the personal details of 180,000 people who phoned police were recorded – four times more than the number of suspected criminals listed on the site.
North Yorkshire Police’s information management system contained data on 181,917 innocent informants, 38,259 suspects and 107,566 victims recorded as aggrieved or ‘vulnerable aggrieved’.
