A member of the crowd can then be heard to say "don't shoot" moments before tear gas and rubber bullets appear to be fired into the crowd. As the bullets are fired an officer can be heard to say: "Back up. We will get her."
The crowd then begins to disperse, covering their mouths as smoke fills the air.
