THE full extent of the torment a nightmare neighbour inflicted on her community was revealed as she was banned from setting foot in the area she terrorised.

The file on Mary Mahoney, 47, was initially opened in 1998 after the first complaints were made about her drunken, abusive behaviour.

Rowdy mother-of-three Mahoney held parties in the garden of her home at all times of the day and night.

Her tirades of abuse, which included threats to kill, were launched at people around the Mackworth estate but particularly those living in Reigate Drive.

A catalogue of details about her intimidating behaviour was compiled by Derby Homes, including 30 incidents within six months reported by one resident.

Mahoney was given five harassment warnings as she drunkenly swore, shouted at and threatened neighbours.

She was finally evicted from her Derby Homes property in March but the housing organisation also wanted her banned from the area because of the anguish she had caused residents living there.

Now, after being given a dossier of evidence compiled over more than a decade, District Judge David Douce has agreed to ban her from parts of Mackworth.

One Reigate Drive resident who welcomed the ban yesterday said her life had been hell when Mahoney had lived in the street.

She said: "I can't begin to explain the stress. It was just the noise, shouting, abuse. She threatened to kill me. It was unbearable.

"Since she was evicted, this street is different. People have come out and now we all chat to each other and are friendly.

"Barriers have come down and that's because she's no longer here."

Another resident said: "When she was drunk there was a lot of noise. She used to have teenagers round her house all the time.

"I think she used to like to think she was still 18 and would drink and smoke with them.

"It's certainly been quieter without her."

Judge Douce agreed to an undertaking Mahoney made in court, meaning she is not allowed to live in the area or go to Reigate Drive for five years.

She is also banned from the Bull and Bush pub for two years after verbally abusing people in the pub in June.

The agreement also means Mahoney cannot harass or abuse another person while in Mackworth. That agreement will be in place for two years. If it is broken, she will be taken back to court.

While some residents wanted the ban to cover nearby shops too, they said it would at least stop her causing trouble in the area.

Derby Homes staff working on a dossier of evidence against her had to persuade reluctant witnesses to speak.

The housing organisation, which manages and maintains homes on behalf of the council, said the cost of Mahoney's behaviour was "incalculable".

Pat Butler, neighbourhood safety officer, worked on the case for more than a year and was receiving near-daily reports of verbal abuse by Mahoney.

She said: "We had 15 witnesses who were very intimidated, which is part of the reason it has taken so long to collect the evidence together to the court stage.

"When we started pulling together the complaints and looking back throughout her tenancy, it was clear the abuse and problems were sustained and serious."

Paul Pegg, of Mackworth Estate Community Association, said Mahoney and her family had caused huge problems in the area.

"She had been causing problems for at least 10 years," he said.

"She was buying drink for people who were underage and was making a nuisance of herself, often with drunken behaviour, and making a real noise.

"When she was evicted things improved dramatically and everyone was over the moon."

Derby Homes said every attempt to help Mahoney and her children, who also caused chaos on the estate, had been exhausted before court action was taken.

She was even signed up to a Family Intervention Programme – a "tough love" scheme which set down strict rules for Mahoney and her children to follow, including attending parenting and alcohol treatment courses.

But it works on a "three strikes and out" policy, so when Mahoney failed to stick to the terms for a third time, she was evicted.

Derby Homes chairman Bob Osler said: "Derby Homes tried to help this family with many different interventions and support mechanisms over several years and it is very disappointing that the mother was not prepared to accept this to help her to improve the lifestyle of herself and her family.

"Her behaviour led to her eviction in March 2011 but unfortunately, she has continued to return to the area and cause problems for others. This action is not a measure we take lightly but need to ensure that the wellbeing of all tenants are considered."

Police had issued five harassment warnings against Mahoney after receiving complaints against her.

The last harassment order was in March this year.

A spokeswoman for Derbyshire police said: "We've worked closely with Derby Homes to improve the quality of life for the residents of Mackworth."
