A Limpopo school principal has been arrested for allegedly raping a former primary school pupil, according to a report on Tuesday.

The principal allegedly had sex with the 13-year-old girl on the back seat of his car on the road between Vuwani and HaMasia villages, outside Thohoyandou, the Sowetan newspaper reported.

The girl's aunt said the girl had confessed to having sex with the principal after a “cat-fight” with a friend.

“I only became aware that all was not right after the victim had a cat-fight with her friend over the principal,” the aunt told the newspaper.

“When I asked them why they were fighting, the friend told me that the victim had accused her of dating the principal while fully knowing that the principal was hers.”
