Then we heard people screaming. It was the weirdest thing possible. Youngsters, boys, were running towards us and stealing phones and pulling bags off people. It was chaos, it was so unreal. How was this even possible?" On Monday, national SAPS spokesperson Brigadier Vish Naidoo said: "We are only aware of one robbery, for which one suspect has been arrested. We have not had other cases reported to us yet." According to Kirk, "The South African Police Service [is] requesting all victims of wrongdoing to file a police report, which we strongly encourage."
