This event happened in 2013 and it still affects the victim

In 2013 was followed and “humped” by a group of young guys on my way home from work. I ran across the street to get away from them and they shouted sexual things and made sexual gestures. Lots of people around who looked at me and did nothing to help. Reported to the police and first question I was asked was “what did I do to provoke them?” Felt angry, violated and vulnerable.
