A Muslim faith school has closed on the first day of an investigation by Ofsted over a "health and safety" issue.
The schools regulator began a two-day visit to Al-Madinah in Derby yesterday.
Acting head teacher Stuart Wilson said the school would close temporarily.
Writing on the school website, he said: "Owing to a health and safety issue, I have taken the decision to close the school to primary and secondary pupils until I am confident that all children are safe on site.
"As parents, you will be informed directly, and on the website, when you are able to send your children back to school. I expect this to be in the very near future.
"Assuring you that we have your children's best interests at heart."
A Department for Education spokesman said: "We were already investigating this school before allegations became public.
"We discussed the problems with Ofsted and it launched an immediate inspection. We are waiting for Ofsted's final report and considering all legal options."
The free school was opened in September 2012.
On its website, it describes "a strong Muslim ethos" with shorter holidays and longer school days "to maximise opportunities for pupil achievement and success".
It adds: "At the centre of our school is a community of pupils, able to enjoy learning in a caring Islamic environment which promotes a culture of high expectations and outstanding performance."
