Eight care workers at an Essex care home have been suspended after secret cameras filmed alleged poor care of residents.
Anglia Retirement Homes said it had launched an independent inquiry into the allegations after the BBC says it filmed staff mocking residents and ignoring their calls for help.
One care worker who was caught slapping a women was "summarily dismissed", it added.
The alleged mistreatment at the Old Deanery in Essex, a 93-bed home in Bocking, was filmed last year by an undercover reporter for the BBC.
- Anglia Retirement Homes told the BBC the incidents involved a "small number of staff".
– Anglia Retirement Homes statement
As soon as the new management team was made aware of the allegations we took immediate action.
We hired an independent law firm to carry out a full investigation as a matter of urgency. Eight staff were immediately suspended, and have not returned to work, pending a full inquiry.
Our priority remains the health and wellbeing of our residents and we have more than 200 dedicated members of staff who remain committed to the highest standards of care."
In its latest inspection in February the Care Quality Commission (CQC) reported the home had too few staff and some residents waited too long for staff to answer their calls.
The company was taken over by new owners last November. Elderly Care Exposed will be broadcast tonight.
