There were two internal investigations , the first one as you say amounted to scurrilous accusations according to them , with strangely not one of the victims spoken to , or contacted on any occasion . The second internal investigation , nobody knows the outcome as they have not advised any findings and it was / is a cunning ploy to evade any questions by replying " No comment due to the on going investigation " which gets them off the hook and out of sticky situations every time. You've got to remember they have a lot of placemen and clever devious bastards on their side in various places and levels in Society as they've been at it for a long time.
