Inside the ground i believe, although hopefully someone will correct me if I'm wrongIf it happened in the ground there should be evidence, you would think the first place you’d put cctv is the directors box, isn’t it alleged to have happened there or was it the car park.…
Trying to think why the club wouldn’t report it, maybe PR at having a go at the fans, creating unrest and division - maybe not wanting to publicise disharmony at the club. Maybe the CEO didn’t want to press charges against the alleged perpetrator, she has that right.
On the opposite side, not reporting is colluding that alleged behaviour as ok and acceptable.
True or not, no win for the club whatever action they take.
