The three suspects — a man and two women — are due in court on Monday, acting police chief Lt Gen Puleng Dimpane said, calling the arrests a “breakthrough”.
Ntimba’s half-naked body was found wrapped in a sheet in Dawn Park last Thursday. Deputy police chief Lt Gen Tebello Mosikili told journalists the killing “appears to be an indication of a murder that stemmed from a relationship… including a possible love triangle”.
Referring to all nine cases, Dimpane said officers were “working tirelessly to bring those responsible to justice”. Police have stressed they have not established whether the deaths are linked or whether a serial killer is responsible, but a team of analysts is examining connections.
Several of the recent victims were discovered partially clothed with injuries. The murders have sparked public anger and fear. Runners gathered in Centurion to honour one victim, Elizabeth Moselakgomo, a jogger who went missing during a routine run. A vigil was also held in Cape Town.
Police have set up a task team and urged women in the Kempton Park area to avoid walking or running alone, particularly in isolated areas.
South Africa has one of the highest rates of gender-based violence in the world.
