The footage showed two boys fighting another 15-year-old boy, who ended up having his head stomped on and receiving a broken nose.
�As a school community we are anti-violence,� Ellenbrook Secondary College principal Peter Havel said.
�Violence and fights among young people are a concern for the entire community and the message that it is not okay should be shared by everyone � parents, schools, police, community groups, sporting clubs, shopkeepers � the whole community.�
The shocking fight last Thursday began when a young male, not from Ellenbrook Secondary College, went to the school in an attempt to confront one of the students.
But the school was tipped off earlier and staff were able to stop the boy entering the school or harming anyone.
Dr Havel said this did not excuse the behaviour of three students in the fight after school, who were each suspended for the maximum penalty of 10 days.
Police also investigated the incident, which took place at Coolamon Oval.
�Most students are not, and have never been, involved in violent behaviour of any description,� Dr Havel said.
�We are firm both in our message to students and our actions to discourage any kind of violence.�
Police became involved prior to the fight attracting media attention and the youths involved have �been dealt with�.
Acting Senior Sergeant Mat Holland said police were working closely with local schools to minimise anti-social behaviour, including fights involving students during and after school.
�Although incidents such as this are rare within Ellenbrook, proactive steps are taken to divert children from this behaviour,� he said.
Senior Sergeant Holland said anyone who became aware of arranged fights between children should immediately advise police and the relevant school.
�Police will investigate all incidents and deal with offenders appropriately,� he said.
