Disturbing footage captures a vicious bully punch a girl in the head — and then drag her along the ground by her hair.
A crowd of other children egg the yob on as they stand and watch the shocking violence.
The aggressive bully has been condemned online, after the video was put on social media and quickly watched by more than 130,000 people.
"If that was my daughter attacking that poor girl and I saw this video, I’d batter the s*** out of her. Nothing worse than a bully," one Facebook user wrote on Monday.
