Johannesburg - Police on Wednesday fired three stun grenades at a group of people in ANC attire that were seen running towards DA marchers on Rissik Street in the Johannesburg CBD.
DA Gauteng premier candidate Mmusi Maimane told reporters that members of the ANC had thrown stones at them.
The DA's march over “real jobs” was stopped around noon as police believed it was too dangerous to continue.
Supporters were told to stop at the corner of Rissik and Marshall streets over concerns that there may be trouble ahead.
An SA Police Service officer told DA supporters the march had ended as it was “too dangerous”.
DA supporters were re-routed back to the Westgate transport hub.
"The protest is being re-routed back to the starting point," said metro police spokesman Superintendent Wayne Minnaar. - Sapa
