According to 'The Sunday Times', at least 10 primary school students, aged between seven and 10, who are at risk of being radicalised and turning to violence.
Some have taken inspiration from jihadi websites or after viewing extremist material in Islamic bookshops, police said.
Other youngsters were identified by their parents after suddenly adopting traditional Muslim dress or espousing extremist views, the report said.
In fact, 228 people aged 15-24, have been referred to the anti-terrorism Channel project, a government outreach programme, after being singled out as "potentially vulnerable to violent extremism", the newspaper said.
"The programme is not appropriate for people who are dangerous or have passed over into violent extremism. The whole purpose is to persuade," Craig Denholm, deputy chief constable of Surrey Police, who oversees the programme, said.
The Channel project was launched by Britain after the 7/7 suicide attacks in London in 2005, when 52 commuters died.
