Is there a ruling on this or is it not in the officials hands?

I hope when I explain this, my question will be clear, if I'm not very clear please let me know and I will try and repost. Game against the number one team in our league at our gym. We end up losing the game by 12 pts because we just basically fell apart, 1 hour and 45mins after the game Im up in my room correcting papers, and a parent of one of my players enters the room. Besides questioning my coaching, she tells me that everytime her daughter took the ball out on the sideline a older gentleman in the first row was grabbing her jersey and making comments. I explained to the mother I had no idea about this or I would have dealt with it. If my player would have toldthe offical what was going on is there anything he/she could do about it? Ironically we played them a month later for the League Championship and won, but before the game I had my Asst. tallk to the officials, and they said they would watch it but could not do anything. I would appreciate your feedback as being a young coach I have never seen this happen before.
