Apparently some of these allegations were looked into in 2007 by Sussex Police, which resulted in no evidence. However, I dont think it was made public, which begs the question, if it had, maybe others would have come forward?!
The only way around this, in my opinion, is for the victims to take a lie detecter test?!
I dunno, I think we may never know.
I do feel sorry for his family atm though :(
