“Worried teachers flag terror fears three times a DAY:

• Teachers worried about extremism issued 741 warnings in two  and a half years
• In some months up to three alerts a day logged with Department of Education
• Highest tally this year, of 76, came in June, the month of London Bridge attack 

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.

On June 3, Khuram Butt, Rachid Redouane and Youssef Zaghba ploughed a van into pedestrians before going on a stabbing spree, killing eight and injuring 48.

The second highest number of warnings, was 63 in May, the month that Salman Abedi  murdered 22 people after an Ariana Grande Concert at the Manchester Arena.

However, this year has seen a drop in the number of concerns logged with Prevent.

In 2015, 390 concerns were raised, the following year saw a significant rise to 517 and as of June this year the figure has dropped to 273.

A Department for Education spokesperson: 'Extremism and intolerance have no place in our society. 

'We established a telephone and email helpline to provide advice and guidance to anyone with questions relating to extremism. 

'Contacts with the helpline include requests for advice, resources and information as well as specific concerns about individuals.

'Where concerns are raised we will investigate further and take appropriate action.'
