One Woman Against Two Men! OMG!

I often see interesting things happen outside my window at work and today was no exception!  I was doing some work and could hear yelling outside  my window.  I looked up and saw a woman yelling at two men.  I couldn’t make out what they were saying, but one of the men kept tugging on her clothes and she would smack him to make him stop.  We were worried about it getting violet so we called our security (who is off duty police officers).  I’m not sure what these men did to this woman but she was really telling them off!  They kept pushing her and she was getting more and more angry.  When she pushed one of the men back, he got really upset an lunged at her and started strangling her.  Just as this happened the cops showed up and the they moved out of my view.
