A 14-year-old boy, who was arrested for intimidating Asian pupils with a metal bar outside his former school, has been banned from his neighbourhood for two years.

Kane Webster, of Upper Hird Street, Keighley, was part of a gang of youths who terrorised residents and businesses in Ingrow, Keighley, Haworth and Oakworth, an anti-social behaviour hearing at Bradford Magistrates’ Court was told yesterday.

The teenager was involved in 18 acts of anti-social behaviour between November, 2009, and June this year, which included the incident at Oakbank School, Keighley.

Magistrates were told the gang had caused trouble outside Haworth Community Centre, the Co-op in Oakworth, Ingrow Fisheries and in Holden Park.

The court heard Webster, who was served an interim Asbo by magistrates in June, was part of a group who threw snowballs containing stones at pedestrians and vehicles, and assaulted a man who tried to challenge them.

He was also present when two youths were chased through Bingley in an incident which saw one man punched to the ground and kicked for his mobile phone.

In March, Webster was identified as the ringleader of a gang in Holden Park, Oakworth, found drinking cans of lager by police.

A month later Webster and another youth stole a mobile phone from a teenager at a skate park and later harassed the victim on a social networking site.

The court heard the teenager was also abusive towards officers when they approached the gang after residents complained of disturbances in Ingrow. Prosecuting on behalf of Bradford Council, Richard Winter, described Webster as a “recalcitrant youth” and told magistrates the Asbo application was being made primarily to protect members of the public in the areas affected.

In mitigation, solicitor Glenn Chivers said Webster had complied with the interim order and his behaviour had improved considerably in the past four months.

His efforts to change his behaviour were greater than those of another gang member, 15-year-old Mark Wood, who was in custody after breaching the terms of an interim Asbo, Mr Chivers added.

Bench chairman Jill Arnold told the court: “We feel it’s necessary to impose the order for two years to protect the public from further acts of anti-social behaviour.”

She told Webster the Asbo offered him a chance to change his life and said “what you have to do is acknowledge what you have done, the people that you have upset and the traumatised in lots of different ways”.

The order, which lasts until August 23, 2012, bans him from Ingrow, Knowle Park – except his house – Oakbank and other surrounding streets between Halifax Road and Pakworth Road, including Queen’s Road – apart from his grandmother’s home, which he can visit if he avoids the exclusion area.

Webster must also stay away from nine other people aged from 15 to 20, including Mark Wood.

After the hearing, PC Mick Wilkinson, anti-social behaviour co-ordinator for the Bradford district, said: “This is an example of the magistrates dealing with an individual who believed they can do what they wanted at the expense of the community. A great deal of local businesses and residents have suffered at the hands of anti social behaviour and this order will allow them to get on with their lives.”
