Victims of crime are being encouraged to investigate offences themselves, an inspection of police forces in England and Wales has found.

In some cases, victims were asked to check for CCTV or fingerprints.

David Styles, whose car was vandalised, told Daniel Sandford about his experience of dealing with the police.
