"My daughter was having nervous breakdowns, she was
scratching herself on her face and thighs," she said.
"As we had just arrived in China I figured it was exhaustion
from moving countries, I didn't worry about it," she said,
adding that only later did she link the unusual behaviour to
abuse.
The fee-paying school declined to provide precise details of
the accusations against the teacher, nor over what period
they allegedly took place. A notice addressed to families
referred to "sexual assaults".
Another mother said she suspected her daughter had been
abused over a period of months, and that cases of abuse of
other children went back as far as five years.
The second teacher, a friend of the first, was "extradited
by Chinese authorities to the United States in December 2012
following an investigation into sexual touching and violence
against minors", the school said in an email.
Shanghai police declined to comment on the cases. The US
consulate in the city also declined to comment.
