A boy of three is among hundreds of children being investigated by police amid a surge in hate crimes .
Figures obtained by the Sunday People under Freedom of Information laws reveal 138 youngsters aged 10 or under were reported for racial or religious abuse last year.
This compared with 70 in 2011.
A nine-year-old boy allegedly told a classmate “My dad told me not to sit next to Jews” and the boy of three was quizzed by police in Manchester for causing harassment, alarm or distress to his victim.
The findings come after a week in which reports of hate crimes rose dramatically in the wake of the EU referendum .
