The Essex teacher motivated to work with troubled children after he was threatened by a six-year-old with a knife

David Simmons' experience forced him into taking action.

A teacher from Essex who was threatened by a six-year-old pupil with a knife has turned his horrific experience into a positive.

The child told David Simmons he wanted to kill him - which was the point the teacher decided he needed to do something.

Now David's working in schools to prevent children being excluded and also running an after school group for vulnerable youngsters.
