Police National Computer

Lord Mackenzie of Framwellgate Excerpts

Tuesday 19th January 2021 Lords Chamber

[Lord Mackenzie of Framwellgate (Non-Afl) [V]]

My Lords, the development of the police national computer, in which I was involved many years ago, was a massive leap in the progress of law enforcement in the UK. As the noble Baroness well knows, the value of real-time data from the PNC is critical to all front-line police officers. DNA and fingerprint evidence is also essential, not only in convicting but in establishing innocence in our courts, in historic and current investigations. For the record, I agree with her that, once taken, DNA should be retained forever. Can she shine any more light on how the error occurred? Can she also give your Lordships any idea of whether it will be possible to recover all or part of the lost data, which is perhaps also held elsewhere?

[Baroness Williams of Trafford (Con)]

I am very happy to give the noble Lord an update: last week the Home Office became aware that, as a result of human error, the software which triggers these automatic deletions contained defective coding and had inadvertently deleted records that it should not have and had not deleted some records which should have been deleted. An estimated 213,000 offence records, 175,000 arrest records and 15,000 person records are now being investigated as potentially having been deleted. It is worth explaining to the House, which I did not do before, that multiple records can obviously be held against the same individual, as the noble Lord will know.

On how we dealt with it, on the same day as the Home Office became aware of it, engineers put a stop to the automated process to ensure that no further deletions took place. All similar automatic processes have also been suspended. Earlier last week, Home Office civil servants and engineers worked very quickly to alert the police and other operational colleagues, and established a bronze, silver and gold command to manage the incident and co-ordinate a rapid response. The noble Lord will have heard me say to two previous speakers just what the process will be over the next few days.
