To ask the Secretary of State for the Home Department pursuant to his contribution on Second Reading of the Crime and Security Bill, 18 January 2010, Official Report, column 35, if he will provide detailed information on each of the 36 cases of DNA data being held on the National DNA database for those previously arrested but not convicted of an offence in which DNA evidence was vital in securing a conviction in cases of (a) rape, (b) murder and (c) manslaughter.
The information given on Second Reading of the Crime and Security Bill was the outcome of an analysis by the Association of Chief Police Officers' Criminal Records Office (ACRO) and the National Policing Improvement Agency (NPIA) of information held on the police national computer, following consultation with the Senior Investigating Officers in each of the 36 cases referred to. In 2008-09 there were at least 79 DNA matches for rape, murder and manslaughter where the original sample was taken for an offence that did not result in a conviction. 36 of these matches were found to have a direct and specific value to the investigation. It is not our policy to release details of individual cases without the explicit consent of the victims or their families. In any case, some of the cases remain before the courts.
