Johannesburg - About three hundred people blocked the R550 and the R554 roads in the south of Johannesburg on Wednesday, metro police said.
“People from Walkerville have blocked off the R550 and people from Eikenhof have blocked off the R554,” said Chief Superintendent Wayne Minnaar.
The two roads were about 11 kilometres away from each other.
The two groups, which together made up about three hundred people, were throwing stones at passing vehicles and burning tyres in the roads.
“The Old Vereeniging road can be used as an alternative,” Minnaar said.
The reason for the protests and reports of injuries could not be immediately confirmed.
No arrests have been made.
