To ask the Secretary of State for the Home Department how many people arrested (a) in each financial year since 1995 and (b) in each month since April 2007, who were (i) under 16, (ii) 16 to 18, (iii) 19 to 21 and (iv) over 21 years at the time of their arrest had their DNA profiles added to the national DNA database; and if she will make a statement.

The information requested on arrests is not available centrally. Information on arrests held by the Office for Criminal Justice Reform is based on aggregated quarterly data collected at police force area level covering persons arrested for recorded crime (notifiable offences) by gender, specific age groups (under 10,10-17,18-20, 21 and over and unknown), ethnicity and by main offence group only. The collection does not record whether DNA profiles were added to the National DNA Database (NDNAD) at the time of arrest.

It is not possible to calculate the information requested by comparing arrest figures with figures for the number of people added to the NDNAD, because if the same person is arrested on more than one occasion during the year, that person will appear in the figures more than once. Also, the age groups used in the arrest figures differ from those in the question.
