The current longest period is 6 years.

Please note, every effort is made to ensure that the figures presented are accurate and complete.

However, it is important to note that data has been extracted from data sources used by this force for police purposes. The detail collected to respond specifically to your request is subject to the inaccuracies inherent in any large-scale recording systems and information assets.

The figures provided therefore are our best interpretation of relevance of data to your request, but you should be aware that the collation of figures/data for any requests may have limitations, and this should be taken into account when those data are used.
Police forces do not use generic systems or identical procedures for capturing the data. For these reasons this response to your questions should not be used for comparison purposes with responses you may receive from other police forces.
