It was about an hour later, and then the murders happened."'The police are failing us'Earlier this month, the bodies of three men, believed to have been set alight, were discovered in the Marikana informal settlement in Philippi East.Following the killings this week, the police announced that plans were in place to engage with Philippi East residents regarding the violence."Taking the law into your own hands is not a solution and is an offence punishable by law," warned Van Wyk.Ward 35 development chairperson Xolisa Pukayi said he wanted Mbalula to visit and intervene."The police are failing us. The criminals are very dangerous," he told News24 on Thursday.Pukayi claimed that police officers had admitted to being scared of the criminals."We are so furious and devastated."
