More than eight out of ten crimes went unsolved last year, a Daily Mail investigation suggests.

Police last year opened 3.9million crime cases, yet our stark analysis today reveals 3.3m were closed with either no suspect ever being identified or coppers unable to prosecute them.

Sex offenders and thieves were among the criminals who evaded justice last year.

Using the data we uncovered, the Daily Mail has built a postcode search tool laying bare the situation in your neighbourhood.

It reveals how many offences actually resulted in action being taken in your LSOA – tiny geographical areas home to around 2,000 people, typically consisting of just a few streets.
