A TEENAGE thug who smashed up a car with a scaffold pole at a school has had his appeal against his sentence rejected.

The terrifying attack took place last May, when the boy, who was high on drink and drugs, smashed every window in a car belonging to the fiance of a teacher who had stepped in to break up an attack on a girl.

The couple drove to the school to try and escape but the teenage thug, who was stripped to the waist, followed them on foot, grabbing a nine-foot metal scaffolding pole on the way The car was left a write-off and the boy then smashed the school doors. Terrified staff barricaded themselves inside the school building, in a cupboard.

The boy was arrested a few days later, assaulting a woman police officer as he was being detained.

He later pleaded guilty to affray, two counts of criminal damage and assault when he appeared before the Swindon youth court, who imposed a one-year detention and training order.

This week the Penhill teenager appealed against the length of the sentence, when the case was heard by Judge Douglas Field.

Rob Ross, defending, said that although his client had been acting violently he did not harm anyone in the incident.

When the car sped off he said that one of the wheels went over his foot and he then went after it grabbing the pole as he went.

He said that his client had been drinking heavily as well as taking ecstasy and cocaine before the incident.

The court heard the boy had suffered a serious sexual assault when he was last in custody and Mr Ross said he had been brought up in a violent environment.

However, Judge Field, who was sitting with two magistrates, rejected the appeal.
