VANDALISM at a Ballarat school left hundreds of students out of class on Monday.
More than 300 students at Ballarat Christian College were told they were not required at school, leaving parents to make alternate arrangements.
The Courier understands the school was closed after graffiti was sprayed on one of the administration buildings.
Ballarat Police arrested two men at the Yarrowee Street school in Sebastopol about midnight Monday.
A 20-year-old Mitchell Park man and a 19-year-old Laverton man were charged with criminal damage.
The incident follows Ballarat Christian College principal Kerry Hutton urging the school community to oppose marriage equality in an email to parents earlier this month.
In the email, Mr Hutton wrote: "The conservative compass points squarely towards the 'no' vote in this issue.
"As a Christian community, many have strong negative views regarding the issue of same-sex marriage."
Mr Hutton also acknowledged not all would share his view and that he did "not wish to cause offence".
The principal declined to comment to The Courier when contacted about the vandalism on Monday.
Victoria Police spokesman Belinda Nolan said she could not comment on the motive behind the attack because the matter was before the courts.
"It would be inappropriate for police to speculate on the possible motivations behind the incident," she said.
"As part of their investigation, detectives will follow up every avenue of enquiry."
The two men have been bailed to appear at Ballarat Magistrates Court on July 10.
