As teachers continue to agitate for round-the-clock security, the Ottos Comprehensive School suffered another break-in, possibly on Monday.

Apart from vandalizing the offices, the perpetrators set fire to the lab destroying important school materials.

The bathrooms were vandalized and canopies were filled with obscene graffiti.

When teachers engaged in industrial action some two weeks ago, security was top on the agenda.

Classes were interrupted bu only for a short time.
