DNA database missing profiles of thousands of prisoners
Almost a million innocent people included on national police DNA records, while many inmates' samples have not been collected

The public would expect the 83,755 people who are currently prisoners in England and Wales to automatically be on the database. If only a "significant majority" have their details logged that would leave potentially thousands, if not tens of thousands, of prisoners not on the DNA database.
Green said that the Home Office admitted almost two years ago that there were 2.3 million people who had been convicted, cautioned or warned and had a record on the police national computer but did not have their DNA profile logged on the database.
