South Africa television and radio presenter Samora Mangesi was allegedly beaten in a racially motivated attack after stopping to help a group of young white men whose car has overturned a few nights ago in the city of Roodepoort.
"They called my friends & I 'monkeys'. When we engaged them on why we were being called such, they beat me up until I was unconscious," Mr Mangesi wrote in a thread on Twitter.
Mr Mangesi, who works for the public broadcaster SABC, claims he was assaulted until became unconscious. His injuries include cuts to his face, mouth and bruising along the left side of his body.
"Even whilst I was being put in the ambulance, one of these guys tried to run my friend over with his bakkie [pick-up truck] and the paramedics had to intervene," he added.
The news has sparked anger on local social media and calls for a police investigation.
