Correction of errors

Two typographical errors have been noted in the published report:

  • at paragraph 6.2, the date should read 2 October 2011 rather than 2 October 2010
  • at paragraph 7.1, the date should read 11 October 2011 rather than 11 October 2010

On 23 October 2011 Mr Adam Scott was charged with an offence of rape by Greater Manchester Police and held in custody. The evidence was a partial DNA profile developed by LGC Forensics (LGC) at its Teddington laboratory and believed, at the time, to be from one sample taken from the victim of the rape.

This was later shown to be an error and the result of contamination during laboratory testing. The Forensic Science Regulator investigated the matter; both to examine the events that led to the error and to determine what lessons could be learned. The regulators report sets out the findings of his investigation.
