A teenage builder has been locked up for his part in the Ravenscliffe disturbances - just two days after the riots in Manningham.

Tony Worby, of Springwood Terrace, Bolton, pleaded guilty to a charge of violent disorder and was sentenced to 21 months in a young offenders' institution at Bradford Crown Court yesterday.

The court heard how 18-year-old Worby hurled missiles at police lines on Monday, July 9.

Sophie Drake, prosecuting, described how during the day officers were deployed to the Harrogate Road area of Ravenscliffe after reports that youths had gathered on the estate two days after the riots in Manningham.

Miss Drake said: "By 9.30pm between 70 and 100 youths were in the area armed with stones and bricks and officers were subjected to the stone throwing.

"Worby, wearing a bright orange jumper, stood out from the crowd."

He was seen smashing concrete slabs to make smaller stones and storing them in a wheelie bin and was then caught on police video running towards the line and throwing missiles, Miss Drake added.

The court heard how three officers were injured that evening and cars driven by Asians were stoned and a couple of Asian-owned businesses also targeted.

Nick Askins, mitigating, said Worby had returned to Bradford that evening after working in Blackpool. He had heard rumours there was going to be an 'invasion' by youths from a different part of Bradford and he went with his friends to defend the estate.

Mr Askins added: "He had no weapon and though he concealed his face with his top this was rather futile and it slipped off. Others had used proper masks."

When violence erupted, Worby was drawn into 15 minutes of stone-throwing, Mr Askins told the court.

He later told police he did not know what he had been doing and accepted it had been foolish.

"Everyone seemed to have been mad. It was just wrong and there is no excuse for it," he told police.

Judge Stephen Gullick said that violent disorder was a serious crime and he had no choice but to impose a custodial sentence.

He said, however, he accepted that Worby's life was at a low ebb following the death of his father, and he urged him to use his talents and skills to better himself once released.
