Three men were shot dead and two left injured after an argument between a group of Indian and white visitors to a bar, allegedly over the size of genitals.
Superintendent Muzi Mngomezulu of the South African police confirmed that five people were arrested in the early hours of Thursday morning in connection with the shootings, which erupted after a confrontation between white and Indian patrons of the bar late on Wednesday evening.
Two of them were in possession of firearms believed to have been used in the killings.
A worker at the bar, who requested anonymity for fear of reprisal, said a customer of Indian origin had remarked to a white customer while they were both at the urinal in the bar that his penis was bigger than that of the white customer.
"After both men returned to their friends, the two groups began swearing at each other before the group of five Indian men left the scene and all returned with firearms. They opened fire and three guys died on the spot. The other two were rushed to St. Augustine's Hospital, where I am told they are critical."
Mngomezulu said the argument is believed to have been racially motivated, although he could not confirm the incident at the urinal.
