Your force will make a number of detentions on immigration grounds. Detainees are usually handed over to the Home Office’s Immigration Enforcement teams.
Please tell me:
(1.) How many people were detained by your force since the start of 2013, until the most recent data available – ideally June 2015. Please provide the data on a month-by-month basis.
(2.) When providing answers to question (1) please include overall figures for those detained on suspicion of committing immigration offences but if you are able to break down the reason for the arrest into more detail (eg the person was detained on suspicion of entering the UK illegally) please do so.
Ideally the format of the data I am seeking would be:
April 2015: Number of detainees held (a) on suspicion of entering the UK illegally X,XXX; (b) for other reasons X,XXX.
May 2015: Number of detainees held (a) on suspicion of entering the UK illegally X,XXX; (b) for other reasons X,XXX.
June 2015: Number of detainees held (a) on suspicion of entering the UK illegally X,XXX; (b) for other reasons X,XXX.
Please find attached our response.
Please note that these data should be interpreted with caution. Comparing numbers of 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.
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 for ad hoc requests may have limitations and this should be taken into account when those data are used.
