Speaking at Scotland Yard, Deputy Assistant Commissioner Steve Rodhouse stopped short of saying he was confident there was never a VIP paedophile ring, but stated that the evidence had not reached the right threshold for charges.
Our role here has been to investigate some serious allegations of crime. We've conducted a very detailed inquiry and our role really has been to assess whether or not there's enough evidence to ask the CPS to level charges.
My conclusion today is we haven't reached that threshold.
We've had a long investigation, a detailed investigation into some serious allegations of crime. It's absolutely right that we fully investigated it. Our role has been to identify whether there was sufficient evidence to ask the Crown Prosecution Service to charge anybody in this case, and our conclusion today is that isn't the case. The evidence doesn't reach that threshold.
