Millions have data stored by police
Millions of innocent people have their details stored on police databases after reporting a crime.
Forces across England and Wales have amassed data about people who dial 999 or non-emergency numbers to report their concerns or pass on information.
West Midlands Police, the second largest force, holds 1.1 million records of people who have reported offences over the past 12 years. Others, including Lancashire, Cleveland, Avon and Somerset, Gloucestershire, West Mercia and North Wales, hold more than 150,000 each.
Senior officers admitted the information could be used against people as part of any future police investigation. They insisted gathering the data was necessary to fight crime, protect the vulnerable and ensure concerns were dealt with properly.
But critics said the vast databases were further evidence of a creeping database state in which information on the innocent was held alongside criminals and suspects.
Evidence of the police databases was collected in a series of requests by the Press Association under the Freedom of Information Act.
The majority of forces said it was not possible to collect the information because the scale of the task was too big. The records included details of millions of victims of crime as well as suspects and offenders.
Forces said personal information was spread across up to 22 databases and warned details of the same person could be recorded several times. They said staff and officers were following guidance published by the National Policing Improvement Agency (NPIA). In some cases, police staff not only record names, addresses and contact details, but ask about the callers' date of birth and ethnicity.
Gus Hosein, of Privacy International, said: "There's a point where the police stop seeing members of the public as the people to be protected and rather see them all as potential criminals. Until now, this only happened in non-democratic states, but I fear that this line has been crossed in ours. This only goes to show how far the last government went in promoting this view that we are all criminals, and my understanding is that while this government has cut the NPIA, which is a first step, a culture change in the way we are governed and protected is the next one."
Ian Readhead, director of information at the Association of Chief Police Officers (Acpo), said forces should only record information relevant to the call. The retired Hampshire deputy chief constable admitted an "amicable exchange of information" could be used against callers in the future but said most people would expect police to hold on to it.
