Four Seasons has suspended four members of staff at Lisnisky in Portadown, County Armagh following abuse allegations.
The action was taken after a man was taken to hospital for treatment of a number of injuries.
Two members of staff have been arrested on suspicion of grievous bodily harm with intent following an alleged incident on 14 April, according to the BBC. They have been released on bail after being interviewed.
A Four Seasons spokesman said: “We are cooperating with the authorities in an investigation into the circumstances that led to one of the residents of Lisnisky Care Home regrettably becoming unwell and being admitted to hospital, on the recommendation of a GP who was promptly called by the home. Four members of staff have been suspended in line with our normal precautionary measures.
“It would be wrong to make any comment or to speculate about the investigation while it is ongoing. However, we would like to give an assurance that we are taking appropriate measures to ensure the safety and wellbeing of our residents, which is always our first consideration. These include an increased level of monitoring and management oversight.”
Police said their investigation was ongoing.
