The Democratic Alliance has discovered another textbook dumping site in Limpopo, provincial spokeswoman Desiree van der Walt said on Tuesday.

She said the books were found next to a bridge in Tzaneen, last week on Friday. The party has opened a case of vandalism against state property with Tzaneen police.

"These criminal acts are insensitive to the needs of the learners, who have already had to spend months without reading material. We hope that more culprits will be brought to book," said Van der Walt.

This was the third criminal charge to be opened for vandalism of state property.

The first was laid at a Giyani police station and the second relates to the destruction of textbooks with public money in Seshego.

Lt-Col Ronel Otto confirmed the DA had opened the case.

She said about 50 books were discovered at the latest dumpsite.

"The Limpopo education department clerk who was charged with malicious damage to property when the first dumpsite was discovered will also be held accountable for this latest incident," said Otto.

The clerk was due to appear in the Giyani Magistrate's Court on Tuesday.

The Limpopo education department denied any knowledge of another dumping site.
