According to Daily Mail report, the girl was stripped daily and routinely assaulted by the pupils in the grounds of the Welsh school.
In a recent interview, the child's mother said, "My daughter was just like any other little girl. I will never forget the look on her face... the fear on her face. I said 'It is OK you can tell Mummy' and then it all started to come out."
"And she was telling me things that I think every mother dreads to hear from their daughter. It was horrendous what she'd gone through," the mother added.
The local council said that due to the young ages of the accused and lack of evidence little action could be taken.
