DNA samples provided by residents during the hunt for the killer of taxi driver Mohammed Arshad have been destroyed by West Mercia Police.
The DNA slides, fingerprints and photographs were securely disposed of to fulfill assurances given by police to people on the Hawkesley Estate and in Monyhull Hall Road during the investigation.
Samples were given voluntarily by males during what was the largest mass screening exercise ever conducted by the force.
It followed the murder of taxi driver Mohammed Arshad who was found stabbed in Wast Hills Lane, Hopwood, on July 22, 2009.
Andrew John Bayliss, aged 29, from Kings Norton in Birmingham is currently serving a life sentence after he was convicted of the murder in April this year.
During the investigation around 2,000 samples were gathered including 700 provided by people living in the area where it was suspected the killer came from.
Detective Superintendent Sheila Thornes, who led the murder case, personally supervised the destruction of the material which was compacted and then incinerated at a specialist waste management company in Birmingham.
