Shahied Mohamed was shot and killed in Joyce Street, following continued gang violence in the area since Saturday.
Mohamed is said to be the cousin of suspected 28s and The Firm gang boss, Ralph Stanfield.
Mohamed was shot multiple times in a drive-by shooting and died at the scene.
In the same street, the 31-year-old daughter of convicted 28s gang boss, Saliem John, was also shot.
The woman, who was shot while standing outside her house, was initially reported dead. But neighbours said yesterday the woman is recovering in hospital from two gunshot wounds to her stomach and leg.
Sergeant Noloyiso Rwexana says no arrests have been made.
Stanfield is the nephew of alleged underworld kingpin Colin Stanfield, who died of cancer in 2004, and is the cousin of convicted 28s boss of Valhalla Park, Saliem John.
Stanfield survived a hit on his life last July when he was shot in Johannesburg.
According to police, three of the 14 bullets fired at his Audi R8 hit Stanfield in the upper body. However, he survived thanks to a bulletproof vest.
Valhalla Park has been tense since the weekend, when a 16-year-old boy from Netreg was shot and killed in the first reported gang-related incident on Saturday.
Five other people were shot and killed until Tuesday.
According to residents, a war is brewing between The Firm (28s), situated in Valhalla Park and the Josters (27s).
A resident, whose five-year-old son was killed two years ago, says he let his child’s killer go unpunished after he was intimidated, but “will not be silenced anymore”.
“We are told when to breathe, how to park, and if we follow the rules, we survive another day, until they change their mind. Die agge rule hier, but now God is taking care of that,” says the father.
“Look how these young men are dying.”
On Wednesday, about 2000 locals shut roads into Bishop Lavis, Valhalla Park and Nooitgedacht to protest for more policing in the area.
