KwaZulu-Natal police are investigating a case of assault with intent to do grievous bodily harm against a group of men who allegedly threw punches and racial slurs at a Durban man on Saturday.

Ndumiso Shezi and his friend Kristen Cheney were leaving a pub in Hillcrest when a group of men and women confronted them.

"They started swearing at me for no reason. I only knew one person in the group and we had no previous issue, so it came as a shock," Cheney told TimesLIVE on Tuesday.

"My friend Shezi then told them not to talk to me like that, when they pounced on him."

She alleged that as the men punched Shezi, they called him the "k-word".

Cheney managed to get Shezi into her car and fled to her parents' home. "I had to get out of there, but the group kept punching my car. My car has dents on it. When we got home, I discovered that both Shezi and I were covered in his blood," she said.
