A Sickening footage of a care home worker punching an elderly dementia patient 11 times while trying to change him has emerged on line.

The incident has caused the care worker to be fired from his job at the Garry J Armstrong care home in Ottawa, Canada.

In the footage, Jie Xiao, 44, can be seen hitting 89-year-old Georges Karam with his left hand while using his other arm to block the patient from hitting back. T

he incident occurred on March 8 this year while Jie was changing Georges incontinence pad.

The elderly patient, who also suffers Parkinson's disease, is seen swiping harmlessly at his care worker before Jie lost his temper and began assaulting him.

The family of the patient took action after seeing a number of unexplained injuries on his body. Georges' grandson Daniel Nassrallah, a lawyer, decided to place a camera in the room to find out the cause of the injuries on the old man's body. Seeing the footage of his granddad getting abused left him horrified.

He told Citizen: "I literally stood up and fell down, my legs gave way because I didn't know how to respond to this. We have a camera on him, and even that doesn't deter him. To me, that's mind blowing.”

Scans revealed that Georges was not seriously hurt. Police have launched an investigation to see if any other patients have been hurt under Jie's care. Asides losing his job, Jie Xiao has pleaded guilty to assault and is due to be sentenced later this year.
