Sussex Jewish leaders are looking into complaints about Jewish Care's Hyman Fine House in Brighton.
Local Jewish representative council president Beryl Sharpe said last week's JC report of an alleged assault on a Hyman Fine resident by another resident highlighted "problems which the council has been aware of for some time. We wish to assure the community that we are doing all that we can to achieve a satisfactory resolution to these problems."
Jewish Care said senior management would be monitoring the home closely over the coming weeks "to ensure that the care on offer is appropriate to the needs of our residents".
Meanwhile, the son of a former respite resident at the home has expressed dissatisfaction with the care provided. Lester Kay complained of a lack of facilities for his father, Cyril, 79, who moved out of Hyman Fine at the beginning of the month.
Mr Kay claimed another resident struck his father with an umbrella but staff said they had not witnessed it.
He also alleged employees had taken more than 40 minutes to change his father's catheter bag. When his father was hospitalised after falling out of bed, Mr Kay did not find out immediately as staff rang the wrong number.
"There's not enough staff at the home," he argued. "And even if they say there is, why should it take so long for them to attend to the residents?"
The charity's director of care and community services, Neil Taylor, said: "Each of Mr Kay's issues is being investigated in detail and a full response will be given. Where any of the issues Mr Kay has raised are upheld, processes will be put in place to ensure that they do not recur. It is very disappointing when we learn that people are unhappy with the care at a home."
