Police officers are now routinely arresting people in order to add their DNA sample to the national police database, an inquiry will allege tomorrow.
The review of the national DNA database by the government's human genetics commission also raises the possibility that the DNA profiles of three-quarters of young black males, aged 18 to 35, are now on the database.
The human genetics commission report, Nothing to hide, nothing to fear?, says the national DNA database for England and Wales is already the largest in the world, at 5 million profiles and growing, yet has no clear statutory basis or independent oversight.
The highly critical report from the government's advisory body on the development of human genetics is published as the number of innocent people on the database is disclosed to be far higher than previously thought ‑ nearing 1 million.
