It is not possible to identify those offences which are knife-related from the data centrally collected on overall recorded crime. However, since April 2007, police forces have been providing separate aggregate data on serious violence involving knives. Home Office statisticians will assess the quality of these data and it is planned that figures for 2007-08 will be published in the main crime bulletin in July 2008.
Available data from the Homicide Index relate to offences currently recorded as homicide where the apparent method of killing is ‘sharp instrument’. Sixty-nine such homicides were recorded in London in each of the 2000-01 and 2006-07 financial years.
