An Australian school principal has apologised after a child "with a particular interest in history and politics" dressed up as Hilter for a Book Week competition.
The student was named among the best dressed and featured in a costume parade at St Philip's College in Alice Springs.
He had asked for permission to dress in the costume and a teacher approved it. But Principal Roger Herbert now says that shouldn't have happened.
"The teacher involved is a respected member of staff who is deeply apologetic for her error in judgement, and the student has an interest in history and politics and did the right thing by getting permission for his "book week" costume."
Mr Herbert said that as the leader of the school he takes full responsibility.
"I apologise unreservedly for any offence that has been caused to students, teachers and the wider community."
A group of Jewish students from Bialik College were also visiting at the time of the costume saga, ABC News reports.
"There were students visiting on an interstate trip and I have personally been in touch with the school and they have graciously accepted our apology."
Twitter was also quick to respond.
