Child abuse can happen right inside the classroom. I just saw this news item on ABS CBN news: Mabel, a 9 year old girl from Silangan Elementary School, in Taguig died after allegedly being made to swallow pencil shavings by her teacher. According to her classmates their teacher thought Madel was the one who had scattered pencil shaving and was punished for it.
This news report Pupil, made to swallow pencil shavings, dies added that:
Although there was no autopsy, acute tonsillitis and asphyxiation pneumonia due to the extreme swelling of throat were stated as the official cause of death.
