From the Mail Online
It is understood this information was already known to police when the investigation into Mills was closed. There had been at least four other discussions between Scotland Yard and the BBC dating back to January 2017.
The allegations were first made to Hampshire police in 2016, involving claims of non-recent sexual offences against a teenage boy. Police have said the alleged victim fell into the age bracket 13 to 16 years old. It is believed Mills and the alleged complainant met online.
The investigation was passed from Hampshire to the Met in December 2016 and Mills, then presenting on Radio 1, was invited to attend a London police station for questioning, rather than being arrested.
So the new information isn't really new and was already investigated.
Think the BBC may ultimately regret their decision. But given the events of this week they may feel they had little choice. The court of social media seems to decide irrespective or facts. Could he have survived all this publicity?
