The official scheme aiming to keep people from being lured by terrorist propaganda may be made compulsory, after a police chief revealed that children as young as five are being shown beheading videos by their families.
Simon Cole, police lead for the deradicalisation scheme Prevent, said police and government have been discussing if some people need to be forced to take part.
Prevent is a controversial programme that aims to divert people from terrorism before they offend, and is currently voluntary. Public bodies such as schools have a duty to report those they suspect are at risk of being radicalised.
There were four lethal terrorist attacks in the UK between March and June this year, sparking a shakeup in counter-terrorism efforts.
