Zanele Moyo was a student at UCT.
“Moyo… was found dead in her private, off-campus flat on Saturday morning,” said UCT spokesperson Gerda Kruger in a statement.
“The cause of death has not been confirmed.”
A police investigation would be carried out.
Lucas said that the 20-year-old was in her second year, majoring in gender, political and international relations studies.
“The death of any student is a tragedy for the entire university. On behalf of the UCT community I extend heartfelt condolences to Professor and Mrs Moyo and their family, as well as to Zanele’s friends, lecturers and classmates.”
Kruger said counselling was available for any of those affected.
Moyo was Zimbabwean President Robert Mugabe’s spin doctor for many years but was recently demoted to education minister.
