Why police officers turned a single theft into 542 cases

Police spent months gathering statements from 542 people who donated money to a youngster who collected £700 for Comic Relief but then kept it.

The case was then recorded as 542 crimes of obtaining money by deception, boosting detection rates even though the youngster only received a warning, the Police Federation conference in Blackpool heard yesterday. It also emerged that an unidentified child in North Wales received a "penalty notice for disorder" (PND) for chalking on the pavement.

The cases were highlighted as absurd examples of the "target culture" reviled by many rank and file officers in England and Wales, which is "criminalising middle England".

The critics say pressure to boost the apparent success rate against crime forces police to make ridiculous decisions and use arrests, cautions or fines for trivial incidents which would not previously have been treated as crimes.

Investigation of more serious offences is then neglected.
