Johannesburg - A police officer was injured during a violent service delivery protest at the Zandspruit informal settlement near Honeydew, northwest of Johannesburg, on Wednesday, police said.
Lieutenant Colonel Lungelo Dlamini said the police officer was hit on the head with a stone and was slightly injured.
He dismissed reports that the police had lost a firearm during a stand-off with protesters.
"It is not true; we have verified it with all members, not one of them has lost a firearm," he said, describing the situation as being tense.
He said 88 people had been arrested for public violence.
Zandspruit informal settlement residents blocked the road with rocks and burning tyres shortly before 06:00 in a protest over service delivery.
The police fired rubber bullets to disperse the crowd when they were pelted with stones.
Television footage showed protesters throwing stones at a police armoured vehicle near a bridge.
Johannesburg metro police said Beyers Naude Drive had been closed to traffic.
"There are still rocks and tyres on the road, it has not been cleared yet," Chief Superintendent Wayne Minnaar said on Wednesday afternoon.
Traffic on Beyers Naude Drive and Peter Road had been diverted to other roads.
