CAPE TOWN - An emotional memorial service was held for UCT student Uyinene Mrwetyana.
The 19-year-old student was raped and murdered in Khayelitsha.
UCT Chancellor Graca Machel called on South Africans to act against perpetrators of sexual violence.
"We need to be much more aggressive. Make them be afraid of walking in public," she said.
"This is a call to every South African. This is not the country we fought for.
"We don't want our people to be afraid. We have the power and the capacity to change this."
The rage over Mrwetyana's murder is widespread.
Anti-gender-violence protesters clashed with police at the International Convention Centre.
Civil society members joined UCT students' protest at Parliament, calling on leaders to take action.
Mrwetyana will be laid to rest in KuCentane village, in the Eastern Cape, on Saturday.
