It's been mentioned on this thread a couple of different times.
"Disturbing footage recently shared on social media shows a person menacing subway riders, kicking a car window and yanking on a woman’s hair as she tried to escape while other straphangers avoid the outburst. The roughly two-minute video posted Wednesday on Twitter by Joel Fischer shows a person who appears to be unwell screaming obscenities, before sitting down and grabbing a J Train rider’s hair as she attempts to move away. “Somebody help me,” the trapped, anguished woman said softly. Meanwhile, fellow commuters either looked on, moved away from or ignored the pair without coming to her assistance."

While it's not this case, the very advice some have given in this case is what this woman tried to do.
Look at her face. Look at her fear. It's hard to watch this without your heart hurting for her. This is how "getting up and moving away" worked for her. The comments at the end of the article are interesting, as they 100% pertain to this very case.
