Council officers have joined a team investigating claims that a mother, who cares for her two disabled foster daughters, has become a victim of housing estate yobs.

Bradford Council has pledged to clamp down on the tearaways who are making Pam Sutton and her family prisoners in their Braithwaite estate home in Keighley.

Keighley police are already on the case involving a catalogue of intimidation, abuse and vandalism over the past 11 years.

Mrs Sutton, 53, has terminal cancer and her disabled foster daughters, Jilly and Jane, both 42, suffer from epilepsy and cerebral palsy.

She has branded their house Cell Block 48 and claims she would feel safer walking alone in New York at 4am than living in Braithwaite.

She said: "Recently they damaged the front of the house and the car and they wrote on our conservatory 'move or die'.

"Jane has a specially-adapted bedroom downstairs because she has cerebral palsy and her bed was right next to the patio window that was smashed.

"The summer house, which I have built for the two girls, was burnt down.

"The girls have never hurt anyone and they don't deserve this sort of abuse.

"I've been fighting this for a long time and the Council's enforcement team and police haven't helped. It's only in the last 12 months that social services have provided any decent support."

Chairman of Braithwaite People's Association Mick Westerman said: "We have seen two police cars, which is an improvement, but we still need to see more positive policing."

Councillor Kris Hopkins (Con, Worth Valley), executive member of Bradford Council's for health and housing, said: "The council will not tolerate this kind of anti-social behaviour and will investigate as soon as problems are brought to our attention.

"We are already working closely with police to deal with youth misbehaviour on the estate."

He said they were paying particular attention to Mrs Sutton's problems.

A Keighley police spokesman said they were investigating the issue and would deal with any specific incidents.
