Teachers concerned about extremism in schools have logged up to three warnings a day with a Government terrorism hot-line.
Staff have raised 1,180 alerts with the Department of Education in two and a half years, making 741 phone-calls and sending 439 emails.
The concerns included pupils being vulnerable to radicalisation and staff members influencing their classes.
The issues were logged with the Prevent line, a watchdog set up to protect vulnerable people from being radicalised to supporting terrorism or becoming terrorists themselves.
The highest amount of warnings raised this year was 76 in June, the month of the London Bridge terror attack. [Daily Mail] Read more
