Crime: Greater London

Volume 475: debated on Wednesday 7 May 2008

To ask the Secretary of State for the Home Department how many (a) administration and (b) sanction detections there were in relation to crimes in London in each of the last 10 years. (192045)

The requested information is given in the following table.

Within the recorded crime statistics, administrative detections are referred to as non-sanction detections. The number of non-sanction detections decreased significantly in 2006-07. This reflects a significant shift away from the use of non-sanction detections, where no further action is taken. Sanction detections are now viewed as the preferred measure, providing a more meaningful comparison of police performance.

Some forces have made a policy decision to significantly limit their use of non-sanction detections in recent years. The greater focus on sanction detections was further emphasised by the move to the use of the sanction detection rate within the police performance assessment framework.

Notes:

1. The coverage was extended and counting rules revised from 1998-99. This will have had an effect on the number of detections recorded. Figures from that date are not comparable with those for 1997.

2. The data in this table is prior to the introduction of the National Crime Recording Standard. These figures are not directly comparable with those for later years.

1 The data in this table takes account of the introduction of the National Crime Recording Standard in April 2002. These figures are not directly comparable with those for earlier years.

2 The large increases between 2002-03 and 2005-06 were as a result of positive action by the Metropolitan Police Service to increase the number of non-sanction detections. The issue of new rules from 1 April 2007, have severely limited the number of incidences when they can be applied. The Metropolitan police had anticipated these changes, issuing their own policy during 2006-07 that limited the use of non-sanction detections, this leading to a significant reduction in non-sanction detection numbers for that year.

3 It should be noted that non-sanction detections that contribute to the percentage change in detection rates have fallen in recent years reflecting a significant shift by many police forces away from recording detections of crime where no further action is taken. For this reason overall detections rates over time are not fully comparable. From April 1 2007 the rules governing recording of non-sanction detections were revised to reduce the scope within which they can be claimed to a very limited set of circumstances.
