This later article has more information.
>Joshua's mother Claire Reape, 26, was told to change her son's hair over the weekend or he wouldn't be allowed back to Abbey Catholic Primary School in Erdington, Birmingham.
It also has a statement from the school:
>A spokesperson for Abbey Catholic Primary School said: 'The school has a strict school uniform policy which all pupils and their families are made aware of when they join the school.
'A child attended school on Friday with a hair style that was unacceptable and his mother was asked to change his hair style in line with school policy.'
It seems a bit heavy handed if he was only given the weekend to change it, and assuming they gave no guidance as to what changes needed to be made over the weekend. However I still think there may be more to this story than we are told here.
