However the Scottish Biometrics Commissioner, Dr Brian Plastow, called on Police Scotland and the Scottish Police Authority (SPA) to review procedures for recording ethnicity when it collects DNA or other biometric data following arrest – and issued a report saying failure to do so correctly was “concerning”.
The report highlighted that where a criminal has been re-arrested, no fresh DNA sample is routinely taken if a lower standard DNA profile was recorded predating 2014 – despite investment that year which gave Police Scotland access to the most advanced DNA analysis facilities available internationally.
Dr Plastow said: “SPA Forensic Services and Police Scotland were unable to provide us with any reliable management information on the ethnicity of anyone held within SDNAD as the database is nearly 30 years old and not designed to record this information.
In 2014, after the establishment of Police Scotland and the SPA, the Scottish Government spent £6 million on the new DNA testing facility, but a decision not to re-test samples predating 2014, means less than a third of offenders’ profiles are currently of the newer DNA24 standard, it was warned.
Less than 1,000 crimes a year in Scotland are solved using DNA – typically murders, assaults and sex offences – and Police Scotland was told to develop a biometrics strategy including cost, to be approved and in place before October 31.
