Elite Vic student questioned over images

One of Melbourne's most prestigious private schools has not ruled out expelling a student under police investigation for distributing "inappropriate images".

A 16-year-old St Michael's Grammar School student has been interviewed by the sexual crime squad over the images.

St Michael's alerted parents to the police probe in an email on Wednesday afternoon.

Head of School Simon Gipson said the college notified police once they were alerted to the issue by a student.

The school did not say whether the student had been suspended but said he would face "severe consequences" if the police investigation confirmed the student breached the school's behavioural expectations.
