"I told her to go away. She threatened me."

woman who threatened me and wouldnt go away- (Upper West Side)

This woman sits around in the park all day, as though she has nothing else to do.

Her and I had an issue and I walked away. She kept comeing over to me and getting in front of my face. I told her to go away. She threatened me. What should I do?

She is always gossiping and telling people what to do who come into the park! It is unpleasant for me to come back and I enjoy the park so much!
Help!
