An example of a case where this independent investigation worked is the Louis Freeh Report regarding Penn State and the Jerry Sandusky sexual abuse scandal.
According to an investigation by the BBC's The Wales Report earlier this week, in 2012, more than 7, 000 Welsh students crossed the border to study outside of Wales - a 13% increase on the year before.
If the ongoing investigation into this matter reveals damning evidence that corraborates the afore-mentioned report, the Newton family and Auburn University will pay a steep price.
The spokesman added that the Met had "sent a report to the Crown Prosecution Service on Thursday as part of our investigation and a copy of this file was also sent to the Independent Police Complaints Commission, as they are supervising our investigation".
