A 16-year-old Limpopo schoolgirl, Mamaila Makhubela, allegedly took her own life after claiming in a suicide note to her parents that she did so because a teacher had told her she was the ugliest girl in class.

The family of the Grade 10 pupil, from Mashao Secondary School in Ga-Ntata village in Bolobedu, Limpopo, said they believed she had died of a drug overdose after being bullied by a teacher at school.

Mamaila’s sister Thabelo Mbedzi, 28, told News24 that she had been found dead in her bedroom early Monday morning. They also found a container of painkillers and a suicide note.
