Johannesburg - A bus has been set alight on the streets of Braamfontein, apparently by Wits University protesters.
Flames leapt out of the bus' windows and smoke was seen billowing through the streets. The blaze was eventually extinguished by emergency services.
Smoking wreckage lay on the road near the bus.
Wits spokesperson Shirona Patel said police were on the scene and that a pastor from Trinity Church was apparently hit by a rubber bullet in the chaos.
There were running battles between students and police as protests moved through the streets of Braamfontein on Monday afternoon. Three protesters were arrested.
Police fired rubber bullets from a Nyala armoured vehicle as it drove past students who pelted it with rocks. The university said three people had been arrested in Braamfontein while two were arrested on campus earlier.
Earlier, police fired stun grenades to disperse students who were pelting private security guards with rocks at the entrance of the Great Hall. The confrontation began after students tried to access the institution's Solomon Mahlangu House and they were blocked by private security.
