I think they do. It's a very serious claim they've made publicly. They should be questioned on why, if this happened as reported, it was considered a serious enough incident to leak to the press but not serious enough to justify reporting to police.
There is still zero evidence from unnamed "club sources" that such an incident occurred. Are you taking the anonymous club sources claims at face value?
I've heard from club sources in the past that Bill Kenwright is a mutant lizard in a skin suit but make of that what you will.
