Agressive Verbal Harassment

I was walking down on Washington Ave near Pacific Street in Prospect Heights around 9:30pm, A man was walking toward me and as he was passing by me he yelled at me “You make me sick, A bitch like you.” I do not know this person at all. I was just walking to get to my destination. He passed by but decided to turn around and followed me for a block until he saw me i was on the phone.
Sadly, I am a Asian woman and this is not my first time experiencing this. I am sick of it and would like to demand the local government to do something about this. Put signs up on the streets to let people know this is illegal.
