Please find attached our response which provides the closest available data to your request.
Please note that these data should be interpreted with caution. Comparing numbers of incidents/crimes can be misleading and does not necessarily indicate the likelihood of someone being a victim of crime. In addition, the number of incidents/crimes recorded in an area over a period of time can be influenced by a number of factors. Consequently statistics on incidents/crimes for one period may not necessarily be a good indicator of future incidents in that area.
Every effort is made to ensure that the figures presented are accurate and complete. However, it is important to note that these data have been extracted from a number of data sources used by forces for police purposes. The detail collected to respond specifically to your request is subject to the inaccuracies inherent in any large scale recording system. As a consequence, care should be taken to ensure data collection processes and their inevitable limitations are taken into account when interpreting those data.
