More than 400 children under the age of 10 have been referred to England and Wales' new deradicalisation programme, which spanned over the last 4 years.
The scheme, called "Channel", was set up after the 7 July London bombings and hopes to divert young people away from radicalisation..
Figures obtained from the National Police Chiefs' Council show that a total of 1,839 aged under 15 were referred to the programme out of concerns they were at risk of extremism.
The programme is a government initiative, which pinpoints young people who appear vulnerable to extremism, and provides aid and support to prevent that from occuring and divert them away from performing terror acts.
Sally Bates, of the National Association of Head Teachers' (NAHT) said, "Itdoes raise a number of concerns and that's where i can understand that referrals are then made from teachers."
However, one parent disagrees. Ifhat Shaheen, said that her 14-year-old son was interrogated by people working on the Channel scheme.
She said, "A teacher's job is to teach children and not to spy on children.
"Schools are meant to be a safe place where you can have open dialogue and discussion.
"It's really heart-breaking to hear that young Muslim children are being criminalised in this way for the wrong reasons and an overreaction. It stigmatises Muslims."
Security Minister, John Hayes, said that the Channel scheme is about protecting and safeguarding young children. It aims to provide support to make sure children are safe and diverted away from extremism.
