This happened a long time ago when I was 16. I was working in an isolated area of the building and another employee came in, engaged me in conversation and then forced me to the ground and assaulted me. Not rape. I told two other employees and the manager, who ummed a bit and then didn't do anything.
Years on, I've now discovered that he's back at that same place in the position of manager. He'll be in daily, constant contact with teens the same age I was at that time and managing a large team, again the same age and circumstances.
I don't know what to do. I could pick him out of a line-up but I don't remember his name or the date or even the month it happened, although I could have a rough guess. The two colleagues I told now live abroad. I feel very uncomfortable knowing that he did this once and is now in a position of authority where he could easily do it again. Would the police even be interested?
