A girl has admitted being part of a gang of seven who carried out a sickening attack on a disabled boy, kicking him in the head and making march around with his trousers around his ankles.
Horrific footage of the brutal beating was filmed by the 15-year-old girl who later bragged about her part in the attack when leaving a voicemail for a friend.
The clips, which were put on video-sharing sites online and were later probed by police, show the 13-year-old boy badly bruised and battered from the beating.
He is seen lying on the ground while a group of older teenagers take turns to kick him in the face and body.
The victim, whose name has not been released, is later seen with his face bloodied and swollen out of shape from the savage beating.
Police unearthed the voicemail message in which the girl laughs as she tells a friend how she and her pals came to beat up the boy
