Fifty-four-year-old Lesley Foy had been sacked from one rest home for roughing up residents but still continued in the care industry, a court heard.
She was found guilty of wilful cruelty and ill treatment of great-grand mother Margaret Mills.
Mrs Mills, who has now since died, was resident at the Chaseside Rest Home, St George’s Square, St Annes, where she was being cared for and treated for dementia.
Foy, of Edgeway, South Shore, was arrested by police following a complaint to the home’s management by whistleblower Anthony Beezer.
He had only been working at Chaseside for three months when he witnessed the ill-treatment handed out to Mrs Mills by Foy.
He was assisting Foy changing Mrs Mills in a ground floor bathroom which Foy locked from the inside.
Mrs Mills became agitated and Foy snapped.
Adrian Hollamby, prosecuting, said that Foy had been found guilty at trial and yesterday appeared at Blackpool magistrates’ Court for sentencing.
He said Foy had lost her temper with Mrs Mills.
Foy slapped the pensioner across the hands and then dug a ring into her hand.
She teased Mrs Mills by offering her a walking stick and then snatching it away several times.
She also pinned the care home resident against a wall while trying to pull her underwear down as Mrs Mills shouted: “Don’t hurt me”.
Finally she degraded Mrs Mills by pushing a used toilet tissue into the woman’s face.
This was witnessed by fellow carer Mr Beezer, who said in evidence: “I have never seen anything like it in my life I was disgusted. It was not right so I went to management.”
He was described in court as looking as if he had “seen a ghost” when he told another staff member what had gone on.
Daniel Harman, defending, said: “My client has suffered a catastrophic loss of her good character.”
“She does not agree with the verdict at the trial but she respects it.
“The victim was very agitated on the day this took place. Mrs Foy knows she will never work in the care industry again.”
Jailing Foy for four months, chairman of the magistrates Eileen Oldroyd told her: “You have no empathy towards your elderly victim.”
“You were in a position of trust but showed no respect towards this vulnerable lady to who you caused great distress.”
After the hearing one of the grand-daughters of Mrs Mills said: “We clapped when we heard the sentence.”
“We wanted justice for our gran.
“We hoped Foy was going to jail but perhaps it’s not long enough.
“She is a callous woman.”
