A shock video has emerged of an elderly man being threatened with castration - after he was forced to hold a sex toy and taunted by an employee.

The sickening footage, which is believed to have been filmed at Cathedral Nursing Home, Lincoln in May 2018 shows the dementia sufferer repeatedly teased about his sexuality.

In the video, a woman can be heard asking the man if he has engaged in any 'sexual relationships' with Jeremy Corbyn.

Before she subsequently claims the Labour leader has said the elderly man has 'impregnated women' and needs to be 'castrated'.

The unsettling footage comes soon after another was released - believed to have been taken at around a similar time - showing a woman tormenting the elderly man.

It shows her asking him if he has gay tendencies, whether he'd like to wear and frilly dress and threatening to take his walking stick.

The woman also threatens to open his curtains and window, saying: 'I'll just ring down the girls and tell them to open your curtains. That's a good idea isn't it? And the window. I'll have the window open.'

She also requests that the man sing a song featuring the words 'I hate people' and 'people are despicable creatures,' before claiming Jeremy Corbyn instructed him to sing it.

Tina Bardsley, 48, was interviewed by police in relation to a video taken inside the care home - after volunatarily attending an interview.

A spokesman for Lincolnshire Police said: 'No one has been arrested and our investigation is ongoing.'

The footage led Lincolnshire County Council safeguarding teams to step in to ensure the safety of residents at the home in Nettleham Road.

A relative of the man in the video told Lincolnshire Live says he believes more than one person was involved in the abuse at the time.

He said: 'To me, the videos do not capture isolated incidents involving just one person. There's more than one person involved and for some reason they think this is funny.

'I think these people have grown up with these personalities - maybe they were bullies at school. Are they bored at work? It looks like these videos are shared between staff.

'It's fun to them but they don't realise the consequences of what they are doing. As a family we are completely shocked and disgusted.'

Linda MacDonnell, adults safeguarding manager for Lincolnshire County Council, said: 'We have been working with the Care Quality Commission and the police to ensure the safety of residents and we continue to help with the investigation.'

Organisations that campaign for better care of the elderly have been quick to condemn the abuse meted out to the man in the home.

In another shock image taken inside the care home, an elderly man is asked to hold a sex toy. Two videos have been released of goings on at the care home, both of which show a dementia sufferer being teased

Jayne Connery, founder of Care Campaign For the Vulnerable, is calling for the mandatory use of CCTV safety monitoring in all UK care and nursing homes.

She said: 'I and our supporters were distressed and appalled to see such emotional and psychological cruelty by a care staff member, towards a vulnerable elderly gentleman living with dementia in a care home.

'The sickening video showing a care worker taunting a resident, highlighted again the urgent need for safety monitoring in all care and nursing homes which would deter such cruel and despicable behaviour from carers who are entrusted with our most vulnerable in care homes.

'I get to visit many care homes during my work and I am so relieved to see the care sector has many dedicated, professional care staff in it - but we should never ever become complacent that this shocking behaviour can not nor does not ever exist.

'The penalties we are seeing when carers accused of abuse and found guilty - receiving a slap on the wrist with a fine has got to stop.

'Why are our elderly denied their human rights when physically and emotionally abused?

'Why are they not counted in with the rest of society? In too many cases the law is not handing out the toughest penalties - a custodial sentence and banned from care - for life.

'As a civilized society are we so blinded by ignorance that one day it could be us?'

Marie Betts, Alzheimer's Society services manager for Lincolnshire, said: 'People with dementia are among the most vulnerable in society and any abuse like this is completely abhorrent and unacceptable.

'Seventy per cent of people in care homes are living with dementia, and they should be able to do so without fear, safe in the knowledge they will be well looked after.

'We know that most staff care deeply about the people they support, but good care homes are undermined when people are abused.

'Health and social care professionals should have all the tools and support required to provide high-quality, person-centred care to people with dementia that maintains their dignity and quality of life.'

The first video to be released shows a woman teasing a resident, asking if he has gay tendencies, whether he'd like to wear and frilly dress and threatening to take his walking stick

A spokesman for Age UK said: 'Any abuse of older people is completely unacceptable, whatever form it may take and whoever the perpetrator may be.

'Whatever the circumstances, we worry that many instances of abuse or neglect of older people go unreported so we would encourage anyone who suspects that an older person is at risk to contact their social services department or the police without delay.'

Cathedral Nursing Home was ordered to make major improvements or risk being shut down following an inspection in February 2018 by watchdog the Care Quality Commission.

Improvements were noted during a re-inspection in July and the CQC has since concluded that while the service was found to be caring and responsive, improvement was still necessary to make the service safer, more effective and better-led.

The home has since been renamed as Cathedral Care Centre and is now owned by St Philips Care Ltd.

A spokesman for the company said: 'St Philips Care is a long established and well regarded care provider in Lincoln taking over Cathedral Care Centre in October last year.

'Whilst we understand the allegations relate to a period prior to our ownership, we are fully committed to support everyone living at the home.

'We will work tirelessly with the authorities to ensure that our residents remain safe and to achieve the right outcome for all involved.'
