Johannesburg - One of the security guards at Oakdale Secondary School said he knew about the "inhumane" conditions under which pupils taught.
The guard was speaking on Monday morning as pupils and the community took to the streets demanding that their school infrastructure be improved.
The furious community had from as early as 3am closed off the roads into and out of their township. A mobile classroom from the school was set alight in the chaos.

The guard, who spoke on condition of anonymity, said the mobile classes in which the pupils learn were problematic due to damage the rain does to the structure.
The man said although he was fairly new at the school, what he had seen was enough to conclude that the situation was not conducive for children to learn under.
