A foiled Melbourne school-ground poison plot and how the education department handled it will be scrutinised by an independent inquiry.
Two girls planned to put poison in the drink bottle of another student, but staff discovered the plan and the girls were suspended, the Herald Sun reports.
But it's since emerged one girl successfully appealed her expulsion and returned to the school while the victim took out a restraining order and later left the school.
"A full independent inquiry has been launched," Premier Daniel Andrews told reporters on Thursday.
"I don't want to see this happening in our schools. I don't want to see this anywhere."
Mr Andrews, a father of three children aged 15, 13 and 11, said parents would rightfully feel angry, worried and concerned if it had happened to their child.
"My heart goes out to that family, and they can be absolutely confident that we will look very closely what went on here," he said.
Opposition education spokesman Tim Smith said a plot to kill a student should have resulted in expulsion.
