Some are already being cynical about whether the young person's denials through their lawyer can be relied on, but here's the thing: if even the so-called victim, who is an adult, says nothing happened, then this greatly reduces the seriousness of the allegations made by The Sun in absence of any further material information. The Sun has already said in response to the young person's statement, rather sheepishly, that it's now up to the BBC to investigate.
As I've been saying in various comments today, too much has been read into little information and many people here have over-egged the pudding without taking a more reasonable view of the information we have. This doesn't reflect well on us.
