This is despite day two of the protests at the school being peaceful throughout most of the day with no stun grenades or rubber bullets fired at the protesters.
However‚ about an hour after classes ended on Wednesday‚ Cosas supporters proceeded towards the alternative entrance where parents were picking up children but were stopped by leaders of the protests who said the situation would turn ugly if they approached the parents.
The police van that was torched belongs to the Public Order Policing in the province.
The people arrested include community members who were seated under a tree as well as a driver transporting junior primary school children home.
The police have deployed more officers around the school premises and have barricaded one street in a bid to restore order.
