A 16-year-old has been arrested at his Victorian private school over a drugs investigation.
Bendigo Police arrested the Girton Grammar School student on Friday.
The school was alerted by police of the pending arrest and fully co-operated, headmaster Matthew Maruff told AAP on Monday.
The youth was interviewed and released pending further investigations, a police spokeswoman said.
The teenager has been expelled from the school, five other students are being questioned by staff about drug use off-campus and have been asked to stay home until the investigation is complete, Mr Maruff said.
Mr Maruff said there was no suggestion any drug activity had taken place at the school.
In a statement on the school's website, Mr Maruff said "we are shocked by this incident".
"Girton Grammar School takes a zero tolerance stance when it comes to anything to do with illegal drugs," the statement read.
"We have a duty of care to our students to make sure that school is a safe place to be so any illegal activity of any kind at the school is unacceptable."
