An independent investigation has been ordered over a foiled plot involving the poisioning of a school student by two of her peers.
The two girls had reportedly planned to put chemicals into the drink bottle of another student, however the plan was stopped by staff and according to the Herald Sun, the girls were suspended.
However, it has since been revealed that one girl managed to successfully appeal her expulsion and returned to the school.
This was despite the fact that the victim had taken out a restraining order, and subsequently the victim left the school.
The incident happened in March last year, with the girls plotting to put stolen chemicals in the bottle "with the intent to kill".
It is understood that Victoria Police investigated, but the victim did not wish to proceed.
Education Minister James Merlino has ordered Independent Office for School Dispute Resolution chair Francis Handy to investigate if correct processes were followed.
