The Khayelitsha house allegedly belonging to the man accused of raping and murdering university student Uyinene Mrwetyana was set alight on Tuesday night.
Angry community members took to the house, located in I-Section, to protest and demand a harsh sentence for the 42-year-old, who allegedly confessed to his crime in court on Monday.
Mrwetyana was raped and bludgeoned to death with a scale inside a Cape Town post office at the weekend. The court ordered on Monday that the man cannot be named as an identity parade has not yet been carried out.
Video clips of the house apparently belonging to the suspect went viral on social media on Tuesday evening.
Police spokesperson Lt-Col Andrè Traut confirmed the blaze.
"This office can confirm that a house in I-Section Khayelitsha was set alight by community members this evening [Tuesday]. The owner of the property cannot be identified. The circumstances surrounding the incident are under police investigation and the suspects are yet to be arrested," said Traut.
