Secret filming by BBC's Panorama has uncovered poor standards of care at one of England's largest care homes.
The filming at the Old Deanery in Essex showed some residents being taunted, roughly handled and one was slapped.
The home said it was "shocked and saddened by the allegations".
Andrea Sutcliffe from the Care Quality Commission, which regulates health services, said: "I'm shocked and really angry about what Panorama have found."
