Principal Jill Farquharson said the school immediately followed procedures in place to manage situations "such as this". The police were involved and they had worked with the school, she said.
"Good news is the student was located and is safe. We have been with her and her family providing support for most of the day."
Mrs Farquharson said the school counsellor was also involved.
"Our support for the family was immediate and we will continue to do all we can for them over the coming days.
"I held a special assembly today to advise the students of the incident and the importance of walking to school with a friend and also keeping in touch via mobile. The safety of our students is our top priority."

"If your child walks home along Gillies Ave or in the Alpers Ave, Kipling Rd vicinity we would recommend that you drop your child off at school and collect your child from school until the person is apprehended," she wrote.
