Table 1 shows the number of subject profiles removed from the national DNA database under the Exceptional Case Procedure, i.e. following a request to the chief officer of the responsible police force from the person concerned, in each month from 16 October 2009 to 30 November 2009.
The table covers subject profiles from English and Welsh police forces and the British Transport police.

The figures in Table 1 show the number of subject profiles added to the National DNA database (NDNAD) by English and Welsh police forces and British Transport police in each month between 16 October 2009 and 30 November 2009, broken down by the police force which took the sample.
The number of subject profiles held on the NDNAD is not the same as the number of individuals. A proportion of DNA profiles held on the NDNAD are replicates— that is, a profile for a person has been loaded on more than one occasion (this may be because the person gave different names, or different versions of their name, on separate arrests, or because of upgrading of profiles). It is currently estimated that 13.8 per cent. of subject profiles held on the NDNAD are replicates. The replication rate of 13.8 per cent. should only be applied over the entire database however, as the replication rate for individual police forces varies considerably. The presence of these replicate profiles on the NDNAD does not impact on the effectiveness and integrity of the database.
