Former King's head lays down the law

Roy Kelley

The former headmaster of King's College in Auckland has suspended 11 students at his new school in Melbourne, for inappropriate behaviour.

The boys at Melbourne Grammar were suspended over end-of-class water bombing antics, the Herald Sun reported.

The students threw water bombs and broke other school rules on Wednesday.

Yesterday headmaster Roy Kelley told the students of their suspension from the elite private school until Tuesday.

The students were involved in so-called "muck-up day" activities gone wrong.

"Muck-up day" is the name given to an unofficial tradition within secondary schools where graduating final-year students are involved with pranks and other stunts on their last official day of school.

Melbourne Grammar said the school felt it had to act.

"I hate the term (muck-up day)," Mr Kelley said.

"It should be celebration time. That's what we like to call it.

"You always have a few slip up at this time of year and it is up to the school to take a strong stance."

Mr Kelley was headmaster at Auckland's King's College from 2003-2009.
