A woman who seduced, robbed and humiliated vulnerable pensioners while posing as their carer has been jailed for four years for her 'grotesque' crimes.

Coraleena Hunter, 36, has already served long prison sentences for using sex to prey on elderly men.

Her latest victim was an 84-year-old disabled pensioner from York, who was in her clutches until neighbours and local market traders raised the alarm.

Prosecutor Andrew Dallas told York Crown Court Hunter had invited herself to the 84-year-old man's flat one night at 10pm.

She forced herself sexually on him as he lay helpless in bed unable to move.

She slept in his bed despite him begging her to leave and stole cash from his bedside drawer when she woke.

After he collected his pension, she pounced on him in an alleyway, pushed him to the ground and stole the cash.

Branding her behaviour 'grotesque', Judge Paul Batty QC told her: 'You have shown absolutely no regard for him, his feelings, his privacy, his life.

'What you have done to him mirrors what you have done before.'

The woman bragged about being the 'carer' of the man who has learning disabilities, cannot read or write, suffers from epilepsy, recently had a heart attack and can only walk with a walking frame.

Passers by saw him reduced to tears by Hunter who rifled through his pockets or took him aside to rob him even when ordered to leave him alone by concerned neighbours.

Hunter, of no fixed address, pleaded guilty to theft, robbery and two burglaries.

She was given an eight-year extended sentence consisting of a four-year prison sentence plus four years' supervision by the probation service.

She was jailed for four years in 2006 for theft and blackmail of a 70-year-old York man with cerebral palsy.

She slept in his bed and threatened to cry rape if he did not let her do what she wanted.

She also stole his money, CDs and DVDs.

In 2010, she was jailed for five years for theft and robbery of victims who were aged 72 and 85.

Shortly before she befriended the 84-year-old man, she had been released from an eight-week prison sentence for offences against a 75-year-old.

Chris Dunn, mitigating, said: 'She has been so significantly damaged by her background and her upbringing she cannot tell right from wrong.

'The only explanation for her crimes is this woman cannot help herself. That isn't her fault. She lacks the facilities we take for granted. I am asking for mercy.'

A psychological report said Hunter may have a personality disorder.

Five members of the public who helped bring her to justice will receive commendations and £100 rewards from the court.

They are neighbours Nicola Sellers, Alistair Fawcett and Oliver Darbyshire, and market traders Carmela and Jo Tolomeo who run Newgate Hog Roast.

Judge Batty said: 'The only good to come out of this case are the actions of the good people of York.'

He heard that Mrs Sellers helped the 84-year-old on a voluntary basis.

She had taken him home after they had had tea together, when Hunter barged into the flat, pushed the victim against the wall, claiming to be his carer.

When Hunter refused to leave, Mrs Sellers set off the warden's alarm and phoned the police as Hunter rifled through her victim's pockets.

The next morning Carmela and Jo Tolomeo tried to stop Hunter taking the 84-year-old away from their market business where he was a regular customer and had just bought his lunch.

Hunter again claimed to be his carer, saying: 'He is coming with me.'

She took him away and robbed him.

Hunter's downfall came when Mr Fawcett and Mr Darbyshire saw her barge into the man's flat, yelling: 'Get out of my house'.
