The FSS is the market leader in the supply of forensic science services to police forces in England and Wales, as well as being a source of training, consultancy and scientific support.
The FSS originally set up and maintained the UK National DNA Database, but it is now run by the National Policing Improvement Agency (NPIA).
The FSS suffered damage to its reputation following the failure to recover blood stains from a shoe in the murder of Damilola Taylor.
Further damage occurred when the FSS failed to use the most up-to-date techniques for extracting DNA samples in cases between 2000 and 2005.
This led the Association of Chief Police Officers (ACPO) to advise all police forces in England and Wales to review cases where samples had failed to give a DNA profile.
