Video footage of the incident shows Miss Fergusson lying on the side of the footpath as another woman sits on top of her, punching her several times.
Miss Fergusson's mother can be seen hitting the woman as she tries to pull her off her daughter, who is screaming. Meanwhile, two men can be seen fighting in a separate incident. Ms Coker alleged one of the men had earlier punched her in the face.
