A vice gang which took over a Bradford pensioner's home to run its drugs and prostitution racket has now been banned from spreading its activities to other parts of West Yorkshire.

The county-wide ban on the two men and two women forms part of anti-social behaviour orders (ASBOs) imposed by the city's magistrates Court, after fears were raised that the gang would shift its operations to surrounding areas.

Interim ASBOs were made in May against Caroline Styslo, 28, and her sister Yvonne, 29, both of Griffe Head Road, Wyke, Anthony Brown, 37, of Evans Tower, Ternhill Grove, Bradford, and Mohammed Hussain, 30, of Howarth Street, Batley.

The court heard then how they took over the home of 76-year-old Jeremiah Horgan at St Blaise Court, off Manchester Road, Bradford, and used it for their activities.

Now the same court has imposed permanent orders on all of them - for five years in the cases of Brown and Caroline Styslo, three years for Yvonne Styslo and two years for Hussain - and extended the restrictions.

The move was sanctioned by deputy district judge Michael Hopkinson after he had read statements from several police community support officers.

One of them, Qaisar Khan, stated that in the early hours of June 27 he and a colleague were on patrol in Richmond Road when they saw Caroline Styslo and an Asian man go into some bushes at the back of Bradford University estates department.

They followed them and found Styslo coming out of the bushes in a state of undress, he said.

On August 4, the same two officers heard noises coming from behind buildings in Angel Way. They found Caroline Styslo with a man in a state of undress.

About five feet away was another man who had started to undress.

Applying for permanent orders on behalf of Bradford Council, Anesh Pema told the court that the four defendants had preyed on vulnerable people, starting with Mr Horgan.

Brown and Caroline Styslo had then moved their activities a little way down the road to prey upon a mentally ill person who had ended up in Lynfield Mount Hospital.

"It is not that they have stopped their activities, it is just that they have moved away from the exclusion zone," said Mr Pema.

The local authority was seeking a county-wide ban on their activities because of the transitory nature of prostitution, he added.

Philip Ainge, for all four, said there was no evidence to suggest the activities would spread to the rest of West Yorkshire.

He suggested that the area covered by Bradford Council would be sufficient.

The activities had been restricted to an extremely small area and Hussain and Yvonne Styslo had not really been involved in any further activity since the interim orders were made, he added.

Announcing his decision, district judge Hopkinson said he had taken into account the type of activity involved and the availability of other red light districts.
