Other passengers were heard lashing out at her for her conduct and the obstruction caused, while MTR staff tried to mediate. Another clip showed heated exchanges between the woman and other passengers, as she made rude hand gestures at people and questioned a staff member trying to ask her to leave if he intended to sexually assault her.
