A horrific video shows the moment a teenage girl was dragged through a field by her hair while being punched in the head.
A watching crowd film the vicious attack on their mobiles and cheer as the victim, Abbie McCarthy, 15, is repeatedly attacked by bullies .
Abbie's mum Carly, 36, from Middleton, Manchester, claims her daughter was forced to move schools in April due to classmates bullying her.
Mum-of-four Carly, a full-time carer for her autistic son, says: "They were pushing her and putting glue into her hair.
"They made Abbie's life hell. She was constantly upset."
