A rape case is being reopened after a DNA mistake which led to a man being wrongly accused of a sex attack in Manchester.

The man was due to stand trial accused of raping a woman at Plant Hill Park in Blackley last October.

But it has emerged that the DNA sample was contaminated in the laboratories of a company called LGC Forensics.

Greater Manchester Police is reviewing some cases in which the same company processed forensic evidence.

GMP Assistant Chief Constable Steve Heywood said the force was made aware on Tuesday that the DNA profile provided by LGC Forensics was "contaminated during the testing process in their laboratories".

The force contacted the Crown Prosecution Service which dropped the case.

Mr Heywood said: "Our sympathies and thoughts are with the victim who has been through a traumatic ordeal.

"This is clearly an upsetting time and we are doing all we can to support her.

"The exact circumstances of how the sample was contaminated at the laboratory are yet to be established but I am determined to discover what has occurred.
