A deputy care home manager danced around a Ryedale dementia sufferer before hauling him out of his chair and biting him between the legs, a court heard yesterday.

Siobahn Koralewski, then 27, was “taking revenge” on an 88-year-old man for breaking her mother Maragret’s shoulder while agitated, it has been claimed. It was also alleged Siobahn forced a woman dementia sufferer to drink leftovers of her daily tea.

Siobahn and Maragret, now aged 30 and 67, both deny four counts of ill-treating residents at the now closed Roundstones home in Filey, between June and November 2012.

Former care worker Jennifer Price described how she arrived in the dining room at 9am to witness the attack on the man. The court heard he was screaming for his daughter and trying to get up and lash out, while Maragret did nothing to stop what was going on.

Ms Price also saw Siobahn slap the man three or four times across the face.

Siobahn then “roughly” put him in the passenger seat of her car and drove him to Cross Lane Psychiatric Hospital in Scarborough.

Ms Price said: “When she got back she told me she had fastened his seatbelt really tight and had the window open all the way there so he got cold.” Ms Price told the jury she would also see Siobahn preparing mixtures of leftover drinks for a 59-year-old woman who suffered from Downs Syndrome, learning difficulties and dementia. She said: “She was making a drink of all the drinks the woman had left – three or four drinks of tea she would not drink during the day.

“The woman was crying because she did not want to drink her drinks. Siobahn put her hand over the woman’s mouth and said ‘shut up’.”

A 91-year-old male stroke victim was supposed to be guided patiently along on his walking frame, but Siobahn walked with him “with her knee driving him forward while she held him up,” Ms Price claimed.

The trial continues.
