A furious grandma whose 12-year-old granddaughter was assaulted on her way home from school says police 'have done nothing' over the attack - despite being provided with video evidence.
Lynn Wilson says her grandchild Summer Watson was 'slapped five times and punched' while on the bus home in December.
The incident was filmed by a teen boy and later posted to Instagram, with the footage showing Summer being hit in the face.
