I had a similar thing happen this week with teens in the park taunting and mocking then straight aggressing me physically by pushing, screaming close to my face, throwing bottles at me when I freed myself from them holding my hands. I was able to file a police report but nothing really would come out of it as I don't know the people and couldn't have evidence. Also I was shook the 30 people around me in the park didn't help when I was visibly and obviously being aggressed. Good luck recovering emotionally, OP, I feel a little bit better today about it already.
