PSNI have launched an investigation into Glenview care home in Portadown, it has been reported.
The BBC reported that the Regulatory and Quality Improvement Authority (RQIA) made an unannounced inspection at the care home on Thursday, with the home's owner Brendan Breen also applying for voluntary cancellation of its registration.
The home has agreed to close.
It's understood the home has 20 residents who will now come under the care of the Southern Health and Social Care Trust, with plans to transfer them to new premises.
Inspection reports dating back to September 2014 had raised a number of concerns with the conditions of the home, according to the BBC.
Among the concerns reported include a lack of infection control, a "robust cleaning schedule" or proper guidance for cleaning staff.
Other issues were said to include poorly maintained bedrooms, with stained beds and soiled carpets.
The PSNI told the BBC the matter was being "jointly investigated" by its Public Protection Branch and specialist social workers from the Southern Health Trust.
Further details of the investigation were not provided but it was stressed that "safeguarding of any vulnerable victim is a priority for the PSNI".
DUP MP for Upper Bann, David Simpson, said he was saddened to see Glenview shut.
“Glenview have been providing high quality care to clients for many years; the closure of the home will be a huge blow to families and many in the local area," he said.
"I want to assure those families that I will do everything that I can to see that their loved ones are found suitable alternative accommodation."
"I have been in contact with the proprietors of Glenview and the Trust to ensure that this transition period is carried out with minimal fuss to clients. This is obviously a very distressing time for them but their safety and wellbeing is paramount and I will continue to work with the Trust to ensure that suitable facilities are identified as soon as possible."
He continued: “Providers are coming under increasing pressure as operation costs are rising and the fees paid by the department do not reflect these spiralling costs. This must be addressed throughout the province as further closures are inevitable and pushing domiciliary care providers to the wall.”
