Her granddaughter Sarah Kinney said she was mortified when she went to visit her. "I didn't recognise her when I went in. It was only through her (sic) sat on the sofa crying, I realised it was my nan."
The care home operator said Gladys was seen by a doctor after the incident, who gave her the all-clear.
