Children embroiled in the Trojan Horse scandal are being left unprepared for modern Britain, according to the Home Secretary.
Theresa May said the actions of a few individuals were harming the future of youngsters from the city.
However, she refused to be drawn on whether there should be police action after it was revealed an investigation had been launched on the back of new evidence about attempts by hardline Muslims to gain control of some city schools.
"I think everyone must look at how it was that this situation came about, where there was a group of people that were acting to try to create an environment which ran counter to British values," she said.
"School is about preparing children for life in the modern world and what we have seen clearly is that a small number of individuals were creating an environment which runs counter to the values of modern Britain. They were not preparing children for life in today's world."
Five schools have been placed into special measures on the back of the Trojan Horse allegations, which have also led to the resignation of a large number of governors and seen two teachers suspended.
Park View Academy in Alum Rock, Oldknow Academy in Small Heath and Golden Hillock in Sparkhill are among those identified.
Now West Midlands Police are investigating if any crimes have taken place.
Mrs May said: "The police have operational independence so it is up to them to decide what to investigate or not - it is not a job for politicians."
The Home Secretary surprised many when she went public with direct criticisms of the then Education Secretary Michael Gove's handling of the Trojan Horse affair earlier this simmer.
In a letter, which was later leaked, she asked Mr Gove: "Is it true that the Department for Education was warned in 2010? If so, why did nobody act?"
She told the Post a report by Peter Clarke, an ex-deputy assistant commissioner of the Met, identified issues at both the city council and the government department.
She said: "The Peter Clarke report came out with a number of recommendations for both the Department for Education and Birmingham City Council.
"They have identified this was an issue that had been raised before and there was a question about how Birmingham had responded.
"One of the things the Secretary of State has announced is there is going to be an education commissioner and Sir Bob Kerslake will be carrying out a review, working with the council."
