Four care workers who ill-treated elderly dementia sufferers at a nursing home will be sentenced today.
Residents were mocked, bullied and tormented because they would have no memory of the abuse, with one man having his foot stamped on deliberately and another tipped out of his wheelchair.
The vulnerable victims were also pelted with bean bags at their heads "for entertainment", jurors at Preston Crown Court heard.
In November, Carol Ann Moore, 54, Katie Cairns, 27, and Gemma Pearson, 28, were found guilty by a jury of ill-treatment or neglect of a person who lacks capacity, under the Mental Capacity Act, after a four week trial.
Moore, the team leader from Lancaster, was found guilty of one count.
Cairns, from Morecambe, was convicted of three charges while Pearson, of Carnforth, was also convicted of tipping another resident out of his wheelchair.
Darren Smith, 35, from Howgill Avenue, Lancaster, admitted eight counts of ill-treatment ahead of the trial.
The offences at Hillcroft nursing home in Slyne-with-Hest, Lancaster, spanned from May 2010 to September 2011 and related to seven men and one woman, all aged in their 70s or 80s, with the eldest aged 85.
The defendants all worked the day shift on the Coniston Unit at the home which housed residents diagnosed with dementia and displaying "challenging behaviour", the court heard.
Kathryn Johnson, prosecuting, told the court that the four ill-treated residents in "varying ways".
"They mocked them, bullied them and on occasions deliberately assaulted them," she said.
Miss Johnson said bean bags should have been used as part of recreational therapy but they were thrown so hard and fast that residents were unable to catch them.
"This caused frustration and anger in the residents, whereas the defendants would laugh," she said.
Smith and Moore would say "they were doing it for their entertainment as they were bored" and if residents objected they "would be subjected to it all the more".
Pearson was seen to tip a resident out of his wheelchair when he failed to stand up, causing him to stumble.
A receptionist and a cleaner both reported to management that Moore had struck a resident, among other concerns about staff behaviour in September 2011.
The defendants were suspended but then reinstated.
And in December 2011 and January and March 2012, the Care Quality Commission (CQC) received anonymous emails about the home.
In May 2012, Lancashire County Council's Adult Services Social Care department made police aware of a complaint of ill-treatment and a multi-agency inquiry began.
Moore, of Ripon Avenue, Pearson, of Hill Street, and Cairns, of Riverview Court, were arrested in October 2012 and told police they were not responsible for any abuse.
They blamed office politics, cliques in work and in-fighting between staff for the claims of abuse and denied all the charges.
Following the convictions, the families of the victims said they thought there had been failings by the owners and management of Hillcroft, Lancashire County Council Adult Services, NHS Lancashire and the CQC.
They said that families, in particular those with relatives in challenging behaviour units, should be able to contribute to periodic reviews of standards.
