Got assaulted by a homeless guy.

It was around 11:00 am, I was crossing the light near Yerba Buena station and a homeless guy was crossing from the other direction; all of a sudden he started running towards me and tried to punch me. I pulled back and ran to get to the other side of the street. There were people around, but obviously nobody cared or did anything. My whole body was shaking and it took me sometime to really process what had happened. I just called my sister and started balling because I did not know what else to do.

I’ve seen that guy around a couple of times after and I’m really scared now. In case he attacks again, what should I do? Any number I can call besides 911? (I don’t have much hope from SFPD)

Edit: Almost got assaulted*
